6 Performance Verification
Test 1. DC Input Resistance 62
Test 2. Bandwidth 63
Performance Test Record 73
This chapter describes two procedures that are used to verify the performance of
the N2750/1/2A probes. The performance verification for the probes consists of
verifying the probe’s DC input resistance and bandwidth.
Due to the very high frequency of the probing system, it is important to carefully
adhere to the techniques and procedures described in this chapter to accurately
measure the performance.
NOTE The performance measured in this procedure is for the probe by itself.
Keysight high performance real-time scopes (and sampling scopes under
certain conditions) will apply probe correction that will further enhance the
performance of the probes.
NOTE The probe amplifier must have an N2776A Differential Browser Tip installed
during the performance verification procedures.
NOTE Keysight recommends a test interval of one year or 2000 hours of operation.
CAUTION
Electrostatic discharge (ESD) can quickly and imperceptibly damage or
destroy high performance probes, resulting in costly repairs. Always
wear a wrist strap when handling probe components and insure that
cables are discharged before being connected.
