NOTE: If a Teledyne LeCroy ProBus equipped oscilloscope is not available, you may use an
alternate oscilloscope that meets the other minimum specifications listed, and the model
ADPPS power supply, to perform the performance verification procedure. The input
termination of the alternate oscilloscope must be set to 50 Ω and the offset or position
must remain at center screen.
Preliminary Procedure
1. Connect the AP033 Active Differential Probe to the female end of the ProBus
Extension Cable. Connect the male end of the ProBus extension cable to Channel 1 of
the oscilloscope.
2. Turn the oscilloscope on and allow at least a 30-minutes warm-up time for the AP033
and test equipment before performing the Verification Procedure.
3. Turn on the other test equipment and allow these to warm up for the time
recommended by the manufacturer.
4. While the instruments are reaching operating temperature, make a photocopy of the
Performance Verification Test Record (located at the end of this section), and fill in
the necessary information.
The warranted characteristics of the AP033 Active Differential Probe are valid at any
temperature within the Environmental Characteristics listed in the Specifications.
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. Make
sure that the ambient conditions meet the requirements of all the test instruments used
in this procedure.
