HP 10400A OPERATING NOTE
COMPENSATiON ADJUSTMENTS
The miniature probes require two adjustment
procedures: one for low-frequency
compensation and one for high-frequency
compensation. Low-frequency compensation
is an operating adjustment and high-frequency
compensation is accomplished periodically,
according to maintenance schedules.
Low-frequency compensation must be
performed before performing high-frequency
compensation.
NOTE
Low-frequency compensation is adjusted
when the probe is first connected to the
oscilloscope. Probe compensation will
usually hold over all the ranges when
used with a Hewlett-Packard
oscilloscope. If the input capacitance of
the oscilloscope changes as ranges are
switched, compensation must be
adjusted each time a new range is
selected.
Low-frequency Compensation
Most Hewlett-Packard oscilloscopes have a
calibrator (square-wave) output suitable for
low-frequency compensation. If your
oscilloscope does not have such an output,
use a square-wave generator set for an
approximate 1 -2 kHz output.
To accomplish low-frequency compensation,
proceed with the following steps:
