    Performance Verification Procedure Use the following procedure to verify that P6131 probe performs as warranted. For a list of the warranted specifications, see page 3. Table 5 lists the test equipment needed to perform the performance verification and adjustment procedures.
  • Page 15 300 MHz output. If you use the probe with a Tektronix 2445 oscilloscope, the bandwidth specification is lower; see Table 1 on page 3. The maximum sensitivity of the 7A42 plug-in is 20 mV/division. When using the 7A42 to check P6131 probes, double the amplitude settings in the procedures to follow.
  • Page 16 4. Adjust the calibration generator variable amplitude control to produce a precise 5-division display on the oscilloscope. 5. Note the oscilloscope deflection error directly from the calibration generator display for the calculation in step 9 below (Example: +1%). P6131 Instruction Manual...
  • Page 17: Adjustment Procedure

    Service Information 6. Remove the coax cable from the test setup. Connect the P6131 probe output to the same vertical input on the oscilloscope. 7. Connect the probe tip through the probe-tip-to-BNC adapter to the standard amplitude output of the calibration generator. (You must remove the light gray probe-body shell before inserting the probe tip into the probe-tip-to- BNC adapter.)
