11
Enable the output of the calibrator.
12
Record the DC amplitude of the square wave and divide 10 into just the
amplitude of the oscilloscope. Verify that the probe gain accuracy is ±2% +
scope gain accuracy. Record the test results as DC Differential Gain
Accuracy in
Table 11 on page 34
.
13
Disable the 9500B’s output.
14
Connect the PV fixture to the N9500B’s
CH1
active head.
15
Configure the oscilloscope to the following settings:
Amplitude Scale (Channel 2): . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 500 mV/div
16
On the 9500B calibrator, configure
CH2
to the following settings:
Type: . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . TRIGGER

On the 9500B, connect the
CH2
active head to channel 2 on the
oscilloscope.
18
Terminate PV fixture’s 50
W
trace with the matched 50
W
terminator.
19
Insert the probe’s dual signal pins into the probe tip.
20
Use a probe positioner to gently place the probe pin tips onto the PV
fixture’s center conductor and ground plane as identified in
Figure 24
on
page 33.
