Enable the output of the calibrator.
12
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

head.
15
Attach the BNC (f)- to- banana post adapter to the BNC feed through
adapter.
16
Attach the differential probe input leads by clipping the alligator clamp to
the BNC adapter banana post.
17
Enable the 9500B’s output.

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
