Using the Probe
Scope Vertical Accuracy
1 Configure the oscilloscope to the following settings:
Amplitude Scale (Channel 1):.......................................................20 mV/div
Amplitude Scale (Channel 2):.....................................................500 mV/div
Time Scale:...................................................................................200 ms/div
Acquisition mode:.......................................................................32 averages
Input impedance:....................................................................................50
Ω
Trigger:...........................................................................................Channel 2
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.
