Overview
TheV850/V851 is a single-width, 6U VME digital delay generator that accepts a single trigger input and generates four or six separately programmable delay outputs. The four or six channel delays may be combined in sequences to create two or three delay-and-width outputs. The module features a 32-bit dynamic range, 40-ps resolution, low jitter, and high rep-rate capability.
All channels are triggered simultaneously, and the module generates a "T0" edge 25 ns after the trigger, and four or six following delays, each programmable from 0 to 167.8 ms.
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 4 and 6 in the V851, can be combined to operate in the width mode.
The V850/V851 delay parameters may be programmed on-the-fly at VMEbus speeds without any generation of erroneous delays. All delay channels can be updated coherently.

Specifications
| CONFORMANCE | ANSI/IEEE 1014-1987 VMEbus specification. VXIC specification, Rev1.4. |
| DEVICE TYPE | Register based slave: A16:D16:D08(EO). |
| POWER REQUIRED |
V850 4-channel version: V851 6-channel version |
| PACKAGING | Single-width, 6U VME, B-size VXI module. |
| TIMING CHANNELS | Four or six timing channels (1 - 4 or 1-6). In DELAY mode, the V850/V851 produces four/six independent delays. In WIDTH mode, channels 1 and 2 (as well as 3 and 4 and 5 and 6) allow the generation of pulses with programmable delay and duration. |
| TRIGGERING | Triggers can be selected from front panel EXT TRG, internal source, or VMEbus command trigger. |
| REP RATE | Up to 2.5MHz |
| INSERTION DELAY | 25ns |
| RESOLUTION | 39.0625 ps LSB (equivalent to a clock rate of 25.6 GHz) |
| RANGE | 32 bits allows a full scale range of 167.7722 ms on all channels |
| JITTER | Less than (50 ps + 1E-9 x programmed delay) RMS |
| ACCURACY | +- (500 ps + timebase stability) |
| TIMEBASE | Ovenized oscillator. Temperature coefficient<10 ppB/deg C; aging below 1ppM/year. Oscillator may be phase locked to a 10 MHz external reference via the front panel CLOCK I/O connector. |
| INPUTS | EXT TRG: Adjustable threshold level +-2.5V, slope, and termination (Hi-Z, 50 ohms to ground). |
| OUTPUTS | One fixed position marker (T0) and four or six delay (1- 4 or 1-6) outputs. In the DELAY mode, a given timing channel is routed to the similarly numbered output. In the WIDTH mode, the width waveform generated timing channels 1 and 2, are routed to output 2, with 3 and 4 routed to output 4, and, for the V851, 5 and 6 routed to 6. All outputs are commonly adjustable for a baseline of 0 to -2.5 volts and amplitude of 0 to +5 volts. The slew rates are better than 2V/nSec |
| CONNECTORS | Std: SMB, Options: LEMO; LEMO with independent NIM outputs |
