PRELIMINARY PROCEDURE

1. Connect the HFP1500 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 30 minutes warm-up time for the HFP1500 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 Per-
formance Verification Test Record (located in Appendix A), and fill in the necessary data.
5. Select the channel to which the probe is connected. Set the oscilloscope scale factor to 20
mV/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 HFP1500 are valid at any temperature within the Environmen-
tal 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.
