Phillips 792 Dual Delay Module
OVERVIEW
FEATURES
- TWO TOTALLY INDEPENDENT DELAY CHANNELS
- TOTAL DELAY OF 12 7 NSEC IN .5 NSEC STEPS
- MONOTICITY IS GUARANTEED FOR EACH CHANNEL
- 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
- 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).
