Performance Verification
This procedure can be used to verify the warranted characteristics of the
ZS4000 High Impedance Active Probe. It tests:
• Output Zero Voltage
• LF Attenuation Accuracy
Performance verification can be completed without removing the probe covers
or exposing the user to hazardous voltages.
NOTE: The correct operation of the ZS4000 controls requires software version
7.1.1.2 or higher. The oscilloscope software version can be verified by going to
Utilities > Utilities Setup > Status. Contact your local Teledyne LeCroy
representative or visit teledynelecroy.com if the software in your oscilloscope
requires updating.
Required Test Equipment
This procedure has been developed to minimize the number of calibrated test
instruments required. Only equipment listed in boldface 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 adaptors or
cables may be required.
The warranted characteristics of the probe are valid at any temperature within
the Operating Environment (p.3) listed in this manual. However, some of the
other test equipment used to verify the performance may have environmental
limitations required to meet the accuracy needed for the procedure. Be sure
that the ambient conditions meet the requirements of all the test equipment
used in his procedure.
NOTE: The function generator used in this Performance Verification Procedure
is used for making relative measurements. Because the output of the generator
is measured with an oscilloscope in this procedure, it is not required to
calibrate the generator.
