On the 9500B calibrator, configure
Type:......................................................................................................TRIGGER
Load:.............................................................................................................50
3
On the 9500B, connect the
oscilloscope. Connect the
oscilloscope
4
On the N9500B, set
output:
Waveform:.....................................................................................square wave
Load:.........................................................................................................1 M
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.
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
4
Attach the differential probe input leads by clipping the alligator clamp
to the BNC adapter banana post.
5
On the N9500B, configure
output:
Waveform:....................................................................................square wave
Load:........................................................................................................1 M
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
