68 73A-270 Arbitrary Pulse/Pattern Generator Module
Equipment
Requirements Oscilloscope (item 1)
Counter/Timer (item 3)
50 BNC Coaxial Cable, two required (item 5)
Prerequisites All prerequisites listed on page 56
All previous Performance Verification Tests
1. Connect TTL OUT A to Ch-2 of the oscilloscope (1 M input impedance).
2. To verify Ch-A operation with the VXIbus TTL trigger lines, Set the
73A-270 for Ch-A to generate a 500 kHz pulse-pattern triggered by an
external trigger from TTLTRG0* and for Ch-B to provide the trigger pulse
on TTLTRG0*. Verify a 500 kHz pulse-pattern and then stop the pattern.

3. Check the remaining TTLTRG1* through TTLTRG7* lines by sending the
commands in table A–6 and verifying a 500 kHz pulse-pattern.
