3
Configure the oscilloscope to the following settings:
Amplitude Scale (Channel 2):.......................................................500 mV/div
4
On the 9500B calibrator, configure
Type:.....................................................................................................TRIGGER
Load:............................................................................................................50
5
On the 9500B, connect the
oscilloscope.
6
Terminate PV fixture's 50
7
Insert the probe's variable pitch signal pins into the probe tip.
8
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 27 Probing Locations on PV Fixture
9
Enable the 9500B's output.
10 Configure the oscilloscope to the following settings:
Amplitude Scale (Channel 1):.......................................................500 mV/div
Time Scale:...........................................................................................2 ns/div
Acquisition mode:..........................................................................Peak Detect
11 Center the trace on the oscilloscope.
12 On the N9500B, configure
Waveform:.........................................................................................sine wave
Load:..........................................................................................................50
Amplitude:.........................................................................................3V pk-pk
Frequency:..........................................................................................800 MHz
13 Measure the peak-to-peak amplitude on the oscilloscope. It should be
greater than or equal to 210 mV – scope vertical accuracy. Record the
test results as Bandwidth in
