Expensive high end equipment tends to have a long life-cycles. Keep using your best electronics on modern computers with the PCI 5V 33MHz and 3.3V 66 MHz PCI slots of the Ndigo Crate 5 and Ndigo Crate 3.

The Ndigo Crate is specifically designed to house up to eight Ndigo digitizers with a single computer while providing adequate space, power and cooling not available in a standard PC.

Synchronize many channels

The Ndigo Crate is specifically designed to house up to eight Ndigo digitizers with a single computer while providing adequate space, power and cooling not available in a standard PC.

The enclosure is specifically designed to operate multiple synchronized cronologic boards in order to create, for example, a high-speed data acquisition system with up to 32 ADC channels. Although it was originally developed for our time interval analyzers (TDCs) and transient recorders, it can of course also be used to accommodate other DAQ cards, GPUs for high-performance computing, storage adapters, or network devices.

The connection of the external chassis to the PC happens over a PCIe 2.0 x16 link with a full-duplex bandwidth of 2x 8 GByte/s. You can add as many Ndigo Crates directly to your PC as you have free PCIe slots available. You can even add more units by daisy-chaining crates!

The PCIe extension is fully transparent. The operating system can not distinguish between boards in the PCIe expansion box and boards inside the PC itself. No drivers are required.

The slot covers are located at the front of the enclosure. As a result, status information is fully visible and your connectors and cables are nicely reachable during operation.

The crate is delivered as a set including an interfacing cable and a low-profile PC link board.

Crate-3 and Crate-5 can be used as PCIe to PCI adapter while providing five additional PCIe slots.

Applications:

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.

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.

Time-Correlated Single Photon Counting

TCSPC, photon counting, time-correlated single photon counting, detection of individual photons, single-photon detectors (SPD), photosensors
Whether in astrophysics, materials science, quantum information science, quantum encryption, medical imaging, DNA sequencing or in fiber-optic communication: Single-photon detectors (SPD) provide a timing signal from which, for example, fluorescence lifetimes of excited matter can be deduced.

atomic clocks comparisons

two-way satellite time and frequency transfer, TWSTFT, coupling of atomic clocks
We are quite proud that our time to digital converters resolve so accurately that they are suitable for comparing atomic clocks.

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.

low energy nuclear physics

LENP in nuclear astrophysics (NAP), cosmology and astronomy
While many aspects of nuclear physics are considered well understood after almost 100 years of research, several challenging questions are still open and under investigation. Our TDCs are used in gas detectors for nuclear physics experiments helping to understand the microcosm of the nucleus.

neutron detectors

Neutron detectors are not only used in the in area of radiation safety, e.g. in reactor instrumentation or special nuclear material (SNM) detection. They are as well employed in fusion plasma physics, particle physics, materials science, and even cosmic ray detection.

quantum research

Quantum research affects many areas of modern science: quantum cryptography, quantum information science, quantum encryption, quantum key distribution (QKD), quantum electro dynamics (QED), quantum computing etc.
Quantum phenomena such as superposition, uncertainty, and entanglement are studied in quantum research with the goal that they can be safely fabricated when needed and made useful in various disciplines.
