Use the following procedures to verify the warranted specifications of the P6250 and P6251 Differential Probes. Before
beginning these procedures, photocopy the test record and use it to record the performance test results. (See Table 7 on
page 35.) The recommended calibration interval is one year.
These procedures test the following specifications:
DC attenuation accuracy
Differential signal range
Analog bandwidth*
Common mode rejection ratio*
Rise time
* These tests require a network analyzer. Alternate test procedures that use a synthesizer and spectrum analyzer are
provided in the Appendix.
Optional procedures are provided to test the following typical specifications:
High voltage rise time
