xHPTDC8-PCIe: 8-channel time-to-digital converter / time tagging device

The xHPTDC8-PCIe is our most versatile TDC. This is the ideal time-to-digital converter for an infinite stream of time stamps.

Don't restrict yourself to classic common start configurations! With the xHPTDC8-PCIe time interval analyzer you can easily set up custom trigger scenarios. The device provides an infinite stream of timestamps - one for each input pulse. You may filter the stream in your own DAQ-software - or make use of the trigger and grouping features provided by xHPTDC8-PCIe.

Like the xTDC4-PCIe, the xHPTDC8-PCIe provides very high-precision measurements with almost no cycle-to-cycle jitter. From this time interval meter, you can expect an RMS error that is very close to the quantization error. Its linearity is also practically perfect!

The inputs accept a wide range of single-ended signaling standards including NIM, TTL, and CMOS.

The PCIe bus master accesses directly a ring buffer in your PC memory, ensuring low CPU load at high data throughput.

Our TiGer timing generator allows you to create digital output pulse patterns on all connectors to control the timing of your experiment.

The newly added 18-bit ADC can monitor an analog voltage in your system in sync with the data acquisition or controlled by an external trigger.

cronologic will support you with drivers for Windows and Linux.

The occurring cycle-to-cycle jitter of the xHPTDC8-PCIe is much lower than the bin size of 13ps. Therefore you can expect an RMS error below 7ps for your measurements.

High precision

The occurring cycle-to-cycle jitter of the xHPTDC8-PCIe is much lower than the bin size of 13ps. Therefore you can expect an RMS error below 7ps for your measurements.
The threshold discriminators can use positive or negative threshold with configurable voltage. This allows you to use the xHPTDC8-PCIe with a wide range of detectors, constant fraction discriminators (CFD) or signal standards in general.

Bipolar

The threshold discriminators can use positive or negative threshold with configurable voltage. This allows you to use the xHPTDC8-PCIe with a wide range of detectors, constant fraction discriminators (CFD) or signal standards in general.
All inputs can also be used to output periodic pulse patterns to control your experimental setup. The exact timing of these is measured by the TDC.

There is no limit to the acquired time interval with this TDC! It will output an infinite stream of timestamps for all incoming pulses. In case you prefer common start or common stop the device can output structured data that mimic these modes.

Versatile trigger windows

Applications:

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.

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.

spectral imaging

spectral image acquisition, X-ray, radiology, photon-counting computed tomography, microscopy, hyperspectral imaging
The currently most advanced spectral imaging technique is based on single photon-counting detectors. Such detectors typically require precise timing measurements and corresponding applications strongly benefit from fast data acquisition electronics.
