V951 6-channel VXI digital delay generator

Digital Delay Generator - V951
  • Delay and width modes
  • 40 (39.0625) picosecond LSB resolution with 32-bit (167.8 ms) full-scale delay range
  • Less than 25 picoseconds RMS jitter typical
  • Adjustable trigger threshold and output levels
  • Insertion delay of 25 nanoseconds
  • Optional NIM level outputs for all delay channels
  • Optional optical outputs for all delay channels

The V951 is a C-size VXI digital delay generator that accepts a single trigger input and generates six separately programmable delay outputs. The six channel delays may be combined in sequences to create three delay-and-width outputs. The module features a 32-bit dynamic range, 40 picosecond resolution, low jitter, and high rep-rate capability.

All channels are triggered simultaneously, and the module generates a "T0" edge 25 nanoseconds after the trigger, and six following delays, each programmable from 0 to 167.8 milliseconds.

The outputs can also be configured to generate widths. This mode uses two channels, 1 and 2, to generate a pulse whose incidence is determined by channel 1's timing value and whose termination is determined by channel 2's timing value. Similarly, channels 3 and 4 , and 5 and 6 can be combined to operate in the width mode.

The V951 delay parameters may be programmed on-the-fly at VMEbus speeds without any generation of erroneous delays. All delay channels can be updated coherently.

The V956 option adds seven optical outputs. The standard version uses 850 nanometer lasers with ST connectors, and will couple a minimum of 250 microwatts into a 50/125 or 62/125 micron multimode fiber. The outputs are DC coupled and follow the corresponding T0 through T6 electrical outputs. User-accessible switches are provided to set the output polarity of each channel to positive, negative, or off.
