DC Common Mode Rejection Ration (CMRR)
1. Set RDPB5000 series probes at low attenuation ration, respectively (10X, 50X,100X).
2. Set 500V DC voltage for signal source, now the voltage output shutoff.
3. Connect the two probe inputs to 500Vvoltage.
4. Connect the probe output to BNC-female- to- dual binding post, and plug into the two
inputs of the digital millimeter.
5. Enable signal source output, respectively record voltage output values; check with the
following chart to calculate whether is within the ranges.
6. Close the calibrator after completion of the test.

Note : High voltage500 V is used during the testing, please pay attention to personal
safety, to reduce voltage fluctuation, be sure to make the calibrator output 500 V high
voltages after the completion of all connections.
