V980 16-channel VXI time-to-digital converter

Time-to-Digital Converter - V980
  • 16-channel, 48-bit, 48-picosecond resolution TDC
  • Measures events up to 6800 seconds before or after common trigger, or 0 to +13,700 seconds after trigger
  • Adjustable trigger levels and edge polarity
  • Usable as a 17-channel independent time-stamper
  • Fast readout available 200 nanoseconds after events
  • Jitter typically below 40 picoseconds RMS
  • Ultrastable, ovenized quartz crystal timebase may be locked to an external source
  • Optional custom internal microengine can qualify and analyze complex timing events

The V980 is a 16-channel time-to-digital converter used to record the time of occurrence of sixteen independent electrical pulse inputs, each measured relative to a single, common reference input. Each TDC input channel can time its event "hit" with 48.82-picosecond resolution and 48-bit dynamic range.

The module has provisions for adjustable input logic levels and selectable input edge polarity.

The V980 employs a highly linear interpolation technique, which requires a minimum of adjustments. Data is available within 200 nanoseconds of the completion of the measured time intervals, and the modules may be cleared and rearmed in less than one microsecond. All features are switch selectable.
