1. Connect probe to oscilloscope.
2. Connect probe tip to oscilloscope
calibrator output (or square-wave
generator).
3. Adjust oscilloscope to display 6 divisions
of amplitude.
4. Use adjustment tool (supplied accessory)
to adjust C1 (through opening in cover of
probe chassis) for the flattest possible
pulse top.
HP 10400A OPERATING NOTE
High-frequency Compensation
The purpose of high-frequency compensation
in probes is to nullify probe rise time loss other
than that added by the probe input
capacitance.
High-frequency compensation requires an
external 10 kHz pulse generator with a rise
time compatible to the system (oscilloscope
and probe). Refer to table 3 for required
transition time of pulse generator before
preforming high-frequency compensation
adjustments. Any pulse generator meeting
the given specification may be used for this
adjustment.
