V850 4-channel VME digital delay/pulse generator

Digital Delay/Pulse Generator - V850
  • 4-channel VME digital delay generator
  • Delay and width modes
  • 40 (39.0625) picosecond LSB resolution with 32-bit (167.8 milliseconds) full-scale delay range
  • Jitter < 25 picoseconds RMS typical from external trigger
  • Adjustable trigger threshold and output levels
  • Insertion delay of 25 nanoseconds
  • Optional NIM level outputs for all delay channels

The V850 is a single-width, 6U VME digital delay generator that accepts a single trigger input and generates four separately programmable delay outputs. The module features 32-bit dynamic range, 40 picosecond resolution, low jitter, and high rep-rate capability. All channels are triggered simultaneously; the module generates a "T0" reference edge 25 nanoseconds after trigger, and four delay outputs, each programmable from 0 to 167.8 milliseconds.

The outputs can also be configured to generate widths. This mode uses paired channels to generate a pulse whose rising and falling edges are determined by channel programming. Up to two such delay+width outputs are available.

V850 delay parameters may be programmed on-the-fly at VMEbus speeds without generation of erroneous delays. All delay channels can be updated coherently.
