Using the Probe
7 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

1 Disable the 9500B’s output.
2 Connect the 50
Ω
BNC feed through adapter to the N9500B’s
CH1
active head.
3 Attach the BNC (f)-to-banana post adapter to the BNC feed through
adapter.
4 Attach the differential probe input leads by clipping the alligator clamp
to the BNC adapter banana post.
5 Enable the 9500B’s output.
6 Configure the oscilloscope to the following settings:
Amplitude Scale (Channel 1):....................................................500 mV/div
Time Scale:........................................................................................2 ns/div
Acquisition mode:......................................................................Peak Detect
7 Center the trace on the oscilloscope.
8 On the N9500B, configure
CH1
to the following settings:
Waveform:...................................................................................sine wave
Load:..................................................................................................1 M
Ω
Amplitude:...................................................................................3V pk-pk
Frequency:...................................................................................200 MHz
9 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
10 Disable the N9500B’s output and disconnect the probe input.
