5. Select the channel to which the probe is connected. Set the oscilloscope scale factor to
20mV/div.
6. Disconnect the ProBus Extender Cable from the oscilloscope. Verify that the scale factor
changes from 20 mV/div to 2 mV/div.
7. Re-connect the ProBus extender Cable to the oscilloscope.
The warranted characteristics of the HFP2500 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 his procedure.
NOTE: The correct operation of the HFP2500 controls requires software version 8.7.0 or higher on
LC series scopes. The software version in the test oscilloscope can be verified by pushing SCOPE
STATUS, then selecting the System menu option.
Functional Check
The functional check will verify the basic operation of the probe functions. It is recommended the
