FAQ
The Ndigo5G-10 is a PCIe-based 4-channel flash-ADC with sample rates up to 5Gs/s and a resolution of 10bits.

The Ndigo5G is a flash-ADC board for the acquisition of short pulses. It was specifically designed for time-of-flight applications like LIDAR or TOF mass spectrometry. With this transient recorder, pulse arrival times can be measured with an accuracy of up to 5 ps together with information about pulse shapes such as area or amplitude.

Extracted pulse data is streamed directly to the main memory at 800MB/s for the lowest latency and largest buffer size.

Four channels with 1.25 Gsps can be acquired independently. Alternatively, two channels can be combined to increase the dynamic range - or a single channel can be acquired with an even higher dynamic range (up to 5 Gsps sampling rate).

The Ndigo5G-10 offers 10 bits of vertical resolution. The Ndigo5G-8 provides a resolution of 8 bits at a lower cost. Analog bandwidth and sample rate are identical to that of the Ndigo5G-10.

Please note: Consider the Ndigo6G-12 for new designs. It provides even higher performance at a similar cost.

cronologic will support you with drivers for Windows and Linux.

Applications:

FLIM

(fluorescence-lifetime imaging microscopy)
The decay time of an excited fluorophore is typically in the range of a few nanoseconds. In fluorescence lifetime imaging the exponential decay of a sample is determined requiring a timing resolution in the picosecond regime.

LIDAR

also known as: LIDAR, LiDAR, and LADAR, "light detection and ranging", "laser imaging, detection, and ranging", "3-D laser scanning", "LIDAR mapping", "airborne laser scanning", ALS
LIDAR Systems emit ultraviolet, visible, or near-infrared light to image objects and measuring the time-of-flight (TOF) of reflected photons. Such systems are used for object detection and tracking in many different fields, ranging from archaeology to agriculture, autonomous vehicles and robots etc.

OTDR

optical time-domain reflectometry, optical time-domain reflectometer, remote fiber testing
In optical time-domain reflectometry the time of the reflections is determined from the reflection loss by measuring from the same end of the fiber how much light returns via the Rayleigh backscatter or is being reflected from individual locations along the fiber.

Quantum Sensing

see also: quantum metrology
Quantum sensing is an overall term that encompasses techniques and methods that use quantum mechanical phenomena to make precise measurements of physical quantities. Thereby, quantum mechanical states and effects are used to improve the measurement accuracy beyond the limits of classical sensors.

TOF mass spectrometry

TOF- & MASS- spectroscopy detectors, TOFMS
In many TOFMS units cronologic TDCs are used to measure precisely the arrival of single ions. From the arrival time, the ion’s time-of-flight is deduced, from which the mass-to-charge ratio of the detected particle can be determined.

Time Domain Reflectometry

TDR, distance-to-fault, DTF
TDR (Time Domain Reflectometry) is an electronic measurement method that measures reflections along a conductor. It belongs to the category of Distance-to-Fault (DTF) measurements. TDR measurements provide meaningful information about the broadband behavior of transmission systems.

fluorescence lifetime correlation spectroscopy

FLCS, FCS, fluorescence lifetime correlation spectroscopy
Fluorescence-correlation-spectroscopy is a highly sensitive optical measurement method. Fluctuations in the fluorescence emission intensity over time are recorded, which are caused by individual fluorophores that pass through the detection volume.

Frequently Asked Questions

product choice

I have no idea whatsoever which measuring card is suitable for my application. Can you advise me on this?

We would be happy to assist you in selecting a board for your application.

For this purpose we need the following information:

How many measurement channels are needed?

What is the required time resolution?

Do you want to measure the area, intensity or shape of the pulse? Or is the time of occurrence sufficient?

Do you prefer a PCIe CEM card housed in a PC, or do you prefer an external device connected to a Thunderbolt / USB4 port?

Are you aiming for the most space-efficient data acquisition integration possible?

Regarding your timeframe, are you only interested in products that are available now, or are you also interested in upcoming products or custom solutions?

The best way would be for you to use one of our inquiry forms and fill it out completely.

input level

In which level should the signals I use range, which I feed to the inputs of the measuring cards?

Please refer first and foremost to our information in the User Guide for the respective product. The following technical specifications are subject to change without notice.

  • Our standard TDCs are AC coupled. The DC base line can be between 0V and 5V for these devices. Short positive and negative pulses with an amplitude of up to 5V can be processed. The discriminator threshold can be set between -1.32V and 1.18V relative to the DC baseline, with a step size of 40 µV. In general, the threshold voltage should be set well above the noise level of the input signal.
  • The inputs of our standard ADCs are AC-coupled single-ended analog inputs. The maximum input voltage is 0.5 V and the input impedance is 50 Ω. The analog offset can be between -0.25 and +0.25 V.

bin size, jitter and RMS

How are bin size, jitter and RMS error related?

The bin size, jitter, and RMS measurement error are all important parameters that play a role in the digital acquisition of time data.

  • The bin size refers to the width of the time windows into which the data is divided during the measurement. The smaller the bin size, the higher the temporal resolution of the measurement. However, if the bin size is too large, there may be an overlap of data between each time window, resulting in an inaccurate measurement.
  • Jitter refers to the deviation in the time it takes for data to arrive at each time window. When jitter is high, data in a circuit can be erratic or inconsistent, resulting in an inaccurate measurement. Jitter is not directly related to bin size and therefore cannot be calculated directly from it. Jitter can be considered as the measure of the temporal variability of the acquired signal edges.
  • The RMS measurement error refers to the average deviation between the actual values of the input data and the values generated by the measurement. The lower the RMS measurement error, the more accurate the measurement.

ADC integration

How can I integrate cronologic ADCs into my measurement setup?

Our ADCs are currently integrated exclusively via their PCIe interface.

pulse width measurement

Do TDCs only provide the arrival time of incoming pulses or also the pulse width?

Since the pulse amplitude is not measured when using TDCs, in many applications a derivation of the pulse intensity from the pulse width comes into question. In these cases, it may be useful to measure the pulse width as well as the arrival time of the pulse. For the acquisition of single photons, however, this is usually not necessary.

The measurement of pulse widths (i.e., a simultaneous measurement of falling and rising pulse edges) is feasible in most cases, but the specifics depend on the type of card in use.

‍

  • The cronologic TimeTaggers are optimally suited for capturing the arrival time in conjunction with the pulse width. They provide (if enabled) timestamps of both the rising and falling edges of the measured pulse. The time difference corresponds to the pulse width.
  • Pulse width measurement is also possible with the xTDC4-PCIe, though it is more involved.
  • The integrated TDCs of the Ndigo5G-10 and the Ndigo6G-12 are also capable of capturing both edges of the pulse.
  • The xHPTDC8-PCIe captures only one edge per pulse, so the pulse width cannot be obtained with this device.

‍

firmware updates

Is it possible to update the firmware of my cronologic product by myself?

Yes, a corresponding program for updating the firmware is part of the driver package for our cards. Caution: Each firmware update requires a new calibration of the card using the provided calibration software. In some cases, it is necessary to provide appropriate input signals for this purpose.

driver download

Where can I find the appropriate driver for my cronologic product?

On the pages containing product information, there is a corresponding tab. Plus on this website, all downloads for our products are listed. This also applies to products that are no longer in our current range.

For Linux support please use this page.

MATLAB

Is it possible to use the cronologic DAQ boards with MATLAB based software?

‍

We provide a C API that can be used to receive a stream of timestamps in almost any programming language. Histogramming and other analysis of the timestamps can be programmed by the user in a few lines of code.

We do not provide a separate interface to MATLAB. Basically, our drivers are intended to be used either directly in C/C++ programs or, when used in other languages, with a C/C++ wrapper that provides the driver's functions in the respective language and converts the data to the respective data format.

Matlab probably offers several ways to use C++ classes. This seems to be a viable way, although it is not trivial.

Another possibility is demonstrated here.

By the way: For basic applications that are rarely called, there is another way to solve the problem as the driver of our measuring cards offers a tool which records the data into a .csv file. This can then be analyzed in MatLab or also Excel. However, the amount of data generated is quite large, so you have to make sure in your own code that the data is really processed in real-time.

golang

Is it possible to use the cronologic DAQ boards with Go based software?

‍

We provide a C API that can be used to receive a stream of timestamps in almost any programming language. Histogramming and other analysis of the timestamps can be programmed by the user in a few lines of code.

We do not provide a separate interface to Go / Golang. Basically, our drivers are intended to be used either directly in C/C++ programs or, when used in other languages, with a C/C++ wrapper that provides the driver's functions in the respective language and converts the data to the respective data format.

‍

Julia

Rust

Is it possible to use the cronologic DAQ boards with Rust based software?

‍

We provide a C API that can be used to receive a stream of timestamps in almost any programming language. Histogramming and other analysis of the timestamps can be programmed by the user in a few lines of code.

Basically, our drivers are intended to be used either directly in C/C++ programs or, when used in other languages, with a C/C++ wrapper that provides the driver's functions in the respective language and converts the data to the respective data format. Wolfgang Löffler has created Rust bindings for our drivers. He has published code on GitHub under the Mozilla Public License that shows how to use TimeTagger4 and HPTDC8 with Rust. It should be easy to port this code to the xTDC4 and xHPTDC8 in case.

Linux

How can I use cronologic hardware most efficiently in Linux environment?

‍

Our Linux-Supportweb page provides drivers and support for GNU/Linux based applications. ‍Please provide us with information about your application and the driver requirements for your Linux distribution and kernel version. Please note that only kernel versions from 5.0 (March 2019) are supported.

Python

Is it possible to use the cronologic DAQ boards with Python based software?

‍

We provide a C API that may be used to receive a stream of timestamps in almost any programming language. Histogramming and other analysis of the timestamps can be programmed by the user in a few lines of code.

In principle, the use of Python based software is possible along with wrappers. Our customers write their own wrappers suitable for their particular application. For example, there is a Python wrapper for the HPTDC8.

‍

infinite stream of timestamps

I want to capture an infinite stream of timestamps instead of time differences related to a common start signal. How can this be performed?

‍

This function is not supported by common-start TDCs. Therefore, in this case we recommend using our xHPTDC8-PCIe, which has been optimized for this application.

ADC synchronization

How many cronologic ADCs can be operated synchronously?

When using one of our Ndigo Crates, up to eight Ndigo5G-10 cards can be mounted and operated in sync. The synchronization of Ndigo6G-12 is currently not possible.

defense

The company I work for is also closely associated with suppliers operating in the defense sector, or we produce military products ourselves. Is cronologic willing to supply us?

As part of our own sales policy, we would like to ensure that our products are not used in weapons systems. If you are considering purchasing our ADCs or TDCs, please let us know how you can ensure that the use of our products for military purposes can be reliably excluded.

formal quote

What do I need to do to get a formal quote?

Please provide us with the following information:

  • Details of the quantity of the desired cronologic products
  • if necessary, information about the desired delivery date
  • Your complete billing address and delivery address including the telephone number of your head office
  • If your billing address is in the European Union: Your VAT number
  • Your FedEx or UPS customer number. Please inform us immediately if you do not have one.
  • Information about your transport insurance. Please inform us immediately if you do not have one.

shipping insurance

Are the goods covered by insurance when they are shipped ?

‍

We ship fully covered unless you specifically tell us that you have external insurance and therefore would not like us to do so.

shipments

How do we ship your goods?

We ship your goods via FedEx or UPS through your account. Thus you have full control over the shipping costs and can use your own conditions with the shipping company. In case you do not have a FedEx or UPS account, we will ship your order via our own UPS account and show the shipping costs separately on your invoice or within our offer. Please note that this procedure usually leads to significantly higher shipping costs. It is financially more worthwhile for you to open a new FedEx or UPS customer account - especially because you can then take advantage of the new customer offers of these shipping companies.

FCA incoterms

What does shipping to FCA Incoterms mean?

The International Commercial Terms are clauses for the interpretation of commercial contract standards. FCA (Free CArrier) is one of the clauses, which exclude the assumption of the costs for the main transport by the seller. In this case, cronologic takes over the handover to the carrier and, if necessary, also the customs declaration.

delivery restrictions

Are there any restrictions regarding the delivery of measurement cards to certain countries?

Our ADCs are classified as so-called dual-use goods, as they could be used for military purposes in addition to civilian applications. TDCs and Crates are not affected by these restrictions.

Regardless of the fact that we at cronologic want to exclude the use of our products for military purposes, the laws of the EU and many other countries restrict exports. Since we have to apply for a General Export Permit for these countries, delivery processes may be delayed or delivery to certain countries may become impossible.

For the application of this export license we need the following documents from you:

  • Exporter declaration
  • Company profile
  • Gegbf. import license (country dependent)

There are countries for which a general export license can be used for the export of dual-use goods. In this case we need documents from you and there will be no further delay:

These include:

  • Australia
  • Japan
  • Canada
  • Liechtenstein
  • New Zealand
  • Norway
  • Switzerland
  • Singapore
  • USA

‍

export license

What documents are required to apply for an export license?

There are countries for which a general export license can be used when exporting dual-use goods.

In this case, we will need documentation from you and there will be no further delay:

These include:

  • Australia
  • Japan
  • Canada
  • Liechtenstein
  • New Zealand
  • Norway
  • Switzerland
  • Singapore
  • USA

As for other countries: To apply for an export license for dual-use goods we need the following documents from you:

  • Exporter declaration
  • Company profile
  • If applicable, an import license (this depends on the country of the importer.)

‍

goods dispatch

How long does it take to receive my ordered goods?

Provided that the ordered goods are products from our standard portfolio and are in stock, it can usually be assumed that the delivery will be dispatched within 14 days after receipt of the order. During this time, the item is subjected to a further detailed calibration and final inspection, packed and made ready for dispatch. Of course, it is always a requirement that all details regarding customs and shipping have been clarified in advance.

import permit

For which purpose is an import permit required and where can I get it?

Governments may impose certain restrictions on the imported goods as well as on their quantity. As a result, import licenses may be required. Such an import license is a document issued by a national government that allows certain goods to be imported into its territory. This is the international import document IC, which you may need to apply for at your customs office. Each import license specifies the quantity of imports allowed, and the total quantity allowed should not exceed the quota.

You need our export declaration to apply for an import permit.

Please find more information on the WTO website.

company profile

Why is a company profile needed and in what form can it be presented?

When trading dual-use goods, a company profile of the company to be supplied must be submitted to the German authorities. This company profile has to be created by you. It can be submitted in the form of company brochures, presentations, excerpts from the website or a self-representation on letterhead with company logo, letterhead or company stamp.

The purpose of this company profile for the authority is to prove the existence of the company as well as, if necessary, to make a prognosis decision on whether the goods are used in the civil or military sector.

It is mandatory to provide the complete address and communication data of your company and the company website. If your company is an affiliated company (such as a part of a holding company), a reference to this is helpful. Please describe the business activities of your company by listing all industries in which you operate and all product groups manufactured.

end-use statement

What is an end-use statement (EUS) and how do I fill out this document?

The end-user certificate (EUC) is a document in which the use of the goods for a specific purpose and, if applicable, the recipient country are documented. This applies exclusively to dual-use goods, such as our ADCs. The signature of the consignee on the end-use declaration is one of the prerequisites for the export of the goods in question. To ensure smooth processing of the shipment of goods, you should complete the designated form, if necessary, and preferably attach your official letterhead to it.

You will receive the necessary forms from us together with instructions on how to fill in the German End-Use Certificate. Further information can be found on the BAFA website.

reseller

We are resellers and need sufficient margin for our services. Can cronologic help us with this?

As a matter of principle, yes, this is possible. In the run-up to our collaboration with companies that consider themselves resellers, we examine their business model in detail. This will take some time. Please provide us with comprehensive information about your company respectively your corporate group, your customers and the complete scope of your product range.

dual use

What is a dual-use item?

Due to their construction or design, dual-use goods can be used for both civilian and military purposes and are thus subject to the export control of the exporting country. The export of an item listed as dual-use usually requires an export license or a general export license from the responsible German authority. With regard to cronologic, this currently only applies to ADCs.

Please find detailed information on the BAFA website.
