Performance Verification
Performance Verification Overview
This procedure can be used to verify some of the warranted characteristics of the WaveLink
Differential Probe.
The recommended calibration interval for differential probes is one year. Test results can be
recorded on a photocopy of Performance Verification Test Record (on page 70) provided at the end
of this manual.
Performance Verification can be completed without removing the probe covers or exposing the user
to hazardous voltages. No adjustments are provided.
In the unlikely event a probe fails performance verification, it can be sent back to the local service
center or the factory. For information on returning the probe, refer to the Returning a Product for
Calibration or Service (on page 46) or Returning a Product to a Different Country (on page 48)
topics as needed.
This procedure tests the WL-PLINK-A or WL-2.92MM with a D1305-A, D1605-A, D2005-A, or D2505-
A. All probe setups are tested at the factory for the following warranted specifications:

Output Zero

Low frequency attenuation accuracy at low and high voltage range

Rise time
The rise time specification has dependency on characteristics of the platform/cable assembly.
Therefore, traceable calibration requires verification with a specific platform/cable assembly
denoted by serial number. The rise time and attenuation accuracy parameters of probe tip modules
utilizing detachable tips have similar dependencies on the individual interconnect lead, which is
serialized. This applies to the D1305-A, D1605-A, D2005-A, and D2505-A amplifier modules:

The rise time specification for the D1305-A and D1605-A are valid with either the WL-PLINK-
A or WL-2.92MM platform/cable assembly provided that they were calibrated together at the
factory at time of shipment.

The rise time for the D2005-A and D2505-A is valid with the WL-2.92MM platform/cable
assembly that was provided at time of factory shipment. Due to the high BW and short rise
time of the probe system, very specialized test equipment and procedures are required for
performance verification of the rise time, and return to a factory service center is required.
