HRMTime CFD

sensL offers a solution for picosecond timing with ultra-fast detectors through the use of a 0.75 GHz Amplifier/Constant Fraction Discriminator (CFD) module.

The sensL CFD module comprises of two independent, fully programmable Constant Fraction Discriminators for interfacing with a wide range of detectors. The module setup parameters can be programmed via the USB or directly by the HRMTime using the sensL GUI or DLL drivers.

Product Features

  • All settings and adjustments are electronic, non-volatile (stored during powered-off state) and performed via USB port. No more dangling cables, tedious cable adjustments, or manual adjustment of multi-turn potentiometers!
  • Internal amplifier has 256 different gain settings allowing input signals to span more than 2 orders of magnitude. This  allows direct interfacing to virtually any detector (PMT, APD, MCP).
  • Very compact, low power,  rugged package allows the CFD to be placed in close proximity  to the detectors and use short signal cables for best performance.
  • Contains two independent channels.
  • Accepts both polarities of the signal
  • Accepts input pulse rise time of 0.050ns to 5ns
  • 750MHz internal bandwidth
  • TTL level output pulse with selectable duration
  • Interfaces directly to HRMTime
  • Software control allows easy storing and automatic optimization of all settings and adjustments
  • SMA input and output connectors
