Teledyne LeCroy WaveLink Differential Probe Series (13-25 GHz) - Manual (Page 65)

Operator's Manual
WL-HBW-A-OM-E Rev B 59
Output zero and attenuation accuracy can be measured in the field and verified with any
platform/cable assembly.
If the probe package includes multiple probe interconnect leads, the best practice is to complete the
entire procedure for each probe interconnect lead. If more than one interconnect lead is being
verified, copy and fill out a separate test record for each platform/cable assembly, amplifier module,
and interconnect lead.
If the probe package includes probe interconnect leads that are not serialized to the amplifier
module and platform/cable assembly, then performance may not be verifiable.
NOTE: It is recommended that the Functional Check be performed prior to the Performance
Verification Procedure to assure all other non-warranted functions perform as specified. See Quick
Functional Check (on page 68) for more information.
Required Test Equipment
The following table lists the test equipment and accessories, or their equivalents, required for
performance verification of the WaveLink Series of High Bandwidth Differential Probes.
The procedure has been developed to minimize the number of parameters requiring calibration in
the test instrumentation. Only the parameters listed in boldface in the Minimum Requirements
column must be calibrated to the accuracy indicated.
Because the input and output connector types may vary on different brands and models of test
instruments, additional adapters or cables may be required.
