Dc Cmrr - Tektronix P5200 Instruction Manual

DC CMRR

1. Set the range of the probe to
2. Set the oscilloscope input coupling to DC, the vertical to 50 mV/div,
and the seconds/div to 200 µs. Center the trace on the display. Set
the acquisition mode to average 32.
3. Attach the BNC-female-to-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 clamps on the differential probe input leads.
5. Twist the input leads together and connect both probe inputs to
the positive terminal of the modified BNC adapter. (See Figure 3
on page 12.)
WARNING.
do not touch exposed metal parts after the generator output is enabled.
6. Set the output of the calibrator to 500 V, and enable the output.
7. Check that the trace on the oscilloscope shifts less than
3.33 divisions (167 mV) from center.
WARNING.
disabled before modifying/disconnecting test setup or connections since the
exposed metal may be at a hazardous potential. it is recommended that the
generator output amplitude be reduced to a minimum prior to disabling the
output.
8. Disable the calibrator output, and disconnect all test equipment.
This completes the performance verification procedure.
