c. Check flatness: Set the oscilloscope sweep for 5 ns/div. Check that the
flatness of the displayed waveform is within 0.15 div after 20 ns from
the rising edge.
d. Change the oscilloscope controls:
Horizontal
Sweep 2 ns/div
Trigger
Slope Negative
e. Check fall time: Check that the fall time of the displayed waveform from
the 10% point to the 90% point is 4.2 ns or less.
4. Check pulse response at 1 V amplitude:
a. Change the oscilloscope controls:
Vertical CH1
CH1 scale 0.2 V/div
Trigger
Slope Positive
b. To change the VX4792 Arbitrary Waveform Generator controls, type:
c. Check the pulse response: Repeat substeps described in 3a through e,
checking the pulse response characteristics shown in Table F–6.
Table F-6: Pulse Response Characteristics for 1 V Amplitude
Characteristics Test Limits
5. End procedure: Remove the connections.
