* BOTH LEMO AND BNC CONNECTORS
DESCRIPTION
The Model 792 uses coaxial cable to provide an accurate and stable means of generating delays to 127 nSEC in a single width NIM module. Since coaxial cable is employed, no power is required and both linear or logic signals may be delayed with excellent fidelity. The configuration of two identical channels allows two signals to be delayed independently, often necessary for coincidence applications. Each channel has seven switches which select the calibrated delays of .5,1,2,4,8,16 and 32 nanoseconds. The total delay is equal to the sum of the switch settings.
GENERAL PERFOR MANCE Input and Output Characteristics 50 ohm impedance throughout; Accepts signals to +/-350 Volts; Input and output ports are interchangeable; LEMO and BNC connectors on both ports. Delay Controls: Seven toggle switches per channel select .5,1,2,4,8,16 and 32 NSEC. Delay equals the sum of the switch settings. Delay Range: Selectable from 0 to 63.5 nSEC in .5 nSEC steps; 127 nSEC with both channels cascaded. Delay Accuracy Better than +/-50 pSEC or +/-.5% whichever is greater, for each delay switch IN. Minimum Delay. 1.9 nSEC +/-100 pSEC per channel, with all switches in the OUT position. Risetime and Falltime: Tr = Tf <= .7 nSEC + (.02 nSEC x delay setting), from 10% to 90% Maximum VSWR: 1.02: 1 to IOOMHZ 1.05: 1 to 250MHz 1.10: 1 to 500MHz Maximum Attenuation: Loss db < (.1 db x # of switches IN) + (.03 db x delay setting), @ 100 MHz. Operating Temperature: -20'C to +850C Packaging: Standard single width NIM module in accordance with TID-20893 (Rev).
