Test 4
This test verifies the minimum swing voltages of the input probes and the
maximum clock rate of the HP 1652B/1653B when it is in the single phase mode.
Specification:
Minimum swing: 600 mV peak-to-peak.
Clock repetition rate: Single phase is 35 MHz maximum (25 MHz maximum for
the HP 1653B).
Clock pulse width: > 10 ns at threshold.

Procedure:
1. Connect the HP 1652B/1653B and test equipment as in figure 3-19. In order
to most accurately measure the amplitude of the test signals from the pulse
generator, high impedance scope probes should be used to look at the signal
levels at the output of the pulse generator.

Note @
In this setup, only eight channels are tested at one time to minimize loading. The
ground lead must be connected to ensure accurate test results. It is recommended
that all eight channel grounds be connected.
