Performance Test Record 80
This chapter describes how to verify the performance of the
N2820A and N2821A probes. The performance verification
requires an N2825A probe head and consists of verifying the
probe’s DC gain.
NOTE The performance measured in this procedure is for the probe by itself.
Agilent high performance real-time scopes apply probe correction that will
further enhance the performance of the probes.
NOTE Agilent 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.
