Using the Probe
2 On the 9500B calibrator, configure
CH2
to the following settings:
Type:......................................................................................................TRIGGER
Load:.............................................................................................................50
Ω
3 On the 9500B, connect the
CH2
active head to channel 2 on the
oscilloscope. Connect the
CH1
active head to channel 1 on the
oscilloscope
4 On the N9500B, set
CH1
to the following settings and enable the
output:
Waveform:.....................................................................................square wave
Load:.........................................................................................................1 M
Ω
Amplitude:.......................................................................................0.1V pk-pk
Frequency:................................................................................................1 kHz
5 On the oscilloscope, select the amplitude measurement and record the
DC amplitude (approximately 100 mV) of the square wave. This
measurement is only the oscilloscope.
DC Differential Gain
1 Disable the 9500B’s output and disconnect the active head from
channel 1 of the oscilloscope.
2 Connect the N2818A probe output to channel 1 of the oscilloscope.
3 Attach the BNC adapter to the 9500B’s
CH1
active head.
4 Attach the differential probe input leads by clipping the alligator clamp
to the BNC adapter banana post.
5 On the N9500B, configure
CH1
to the following settings and enable the
output:
Waveform:....................................................................................square wave
Load:........................................................................................................1 M
Ω
Amplitude:....................................................................................................1V
Frequency:...............................................................................................1 kHz
6 Enable the output of the calibrator.
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
Gain Accuracy in
Bandwidth
1 Disable the 9500B’s output.
2 Connect the PV fixture to the N9500B’s
CH1
active head.
