• 6-channel digital delay generator in a 6U, register-based VME module.
• Delay and width modes.
• 40 (39.0625) picosecond LSB resolution with 32-bit (167.8 ms) full-scale delay range.
• 50 pSec jitter.
• Adjustable trigger threshold and output levels.
• Insertion delay of 30 nSec.

The Model V851 is a single-width, 6U VME module. It accepts a single trigger input and generates six separately prorammable delay outpus. The six channels of delay may be combined in sequences to create three delay-and-width outputs. The module features a 32-bit dynamic range, 40-pSec resolution, low jitter, and high rep-rate capability.

All channels are triggered simultaneously, and the module generates a "T0" edge 30 nSec after the trigger, and six following delays (1 through 6) each programmable from to 0 to 167.8 ms.

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

The V851 delay parameters may be programmed on-the-fly at VME-bus speeds without any generation of erroneous delays. All six delay channels can be updated coherently.
