Connect the 1159A to CH1 of the oscilloscope.
2 Load 1159CAL0.
3 Connect the 1161A to the output of the function generator and CH4 of
the oscilloscope.
4 Setup the test equipment as shown in the following table. Connect the
1161A probe to CH4 of the oscilloscope. Measure the amplitude on CH4.
5 Select Auto Zero under the probe menu.
Do not connect the probe tip to the fixture when Auto Zero is performed.
