Using the Probe
3 Configure the oscilloscope to the following settings:
Amplitude Scale (Channel 2):.......................................................500 mV/div
4 On the 9500B calibrator, configure
CH2
to the following settings:
Type:.....................................................................................................TRIGGER
Load:............................................................................................................50
Ω
5 On the 9500B, connect the
CH2
active head to channel 2 on the
oscilloscope.
6 Terminate PV fixture’s 50
Ω
trace with the matched 50
Ω
terminator.
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
.

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
CH1
to the following settings:
Waveform:.........................................................................................sine wave
Load:..........................................................................................................50
Ω
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
14 Disable the N9500B’s output and disconnect the probe input.
