Appendix C: Performance Verification

1.Install test hookup and set test equipment controls:

a.Hook up termination board: Connect the AWG2021 rear ECL digital data output through a digital data output cable to the termination board (see Figure C-20).

b.Hook up power supply: Connect the power supply output through the test leads to the GND TP100 and ±2VD TP120 terminals on the termination board.

c.Hook up oscilloscope:

￿Connect the oscilloscope probe to the CH1 vertical input.

￿Connect the probe ground-clip to the GND TP200 terminal on the termination board.
