xHPTDC8-PCIe

Time-to-digital converter xHPTDC8-PCIe

Our most versatile TDC combines the precision of the xTDC4-PCIe with the channel count and flexibility of the HPTDC8-PCI.
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.

TiGer timing generator

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

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.
Measure the amplitude of a static analog input signal at defined time intervals or triggered by an external signal.

Voltage monitoring ADC

Measure the amplitude of a static analog input signal at defined time intervals or triggered by an external signal.
You can block inputs from being measured for a certain period of time relative to other input pulses. This reduces buffering requirements and CPU load.

Veto or gate inputs

You can block inputs from being measured for a certain period of time relative to other input pulses. This reduces buffering requirements and CPU load.

Don't restrict yourself to classic common start configurations! With the xHPTDC8-PCIe your 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. You can expect an RMS error very close to the quantization error. Its linearity is also practically perfect!

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