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:
