7. Set the generator to 100 MHz, and set the oscilloscope to
5 ns/division. Check for ≥ 2.1 V amplitude.
8. Disconnect the set up.
DC CMRR
1. Set the attenuation of the probe to 50X.
2. Set the oscilloscope input coupling to DC, the vertical to
50 mV/div, and the seconds/div to 200 s. Center the trace on the
display. Set the acquisition mode to average 32.
3. Attach the BNC-female-t o-dual-banana adapter to the DC output
of the generator (front of Wavetek 9100). Attach the modified
BNC adapter to the BNC-female-to-dual-banana adapter.
4. Attach the plunger cla mps on the differe ntial probe input leads.
5. Twist the input leads together as shown in Figure 3 on page 13,
and connect both probe inputs to the positive terminal of the
modified BNC adapter.
6. Adjust the offset on the probe output to zero.
WARNING. Generator produces hazardous voltages. To avoid risk of
shock, do not touch exposed metal parts after the generator output is
enabled.
7. Set the output of the generator to 500 VDC.
8. Enable the output.
9. Check that the trace on the oscilloscope shifts less than 3.33
divisions (167 mV) from cent er.
10. Disable the generator output.
