The
adjustment
program
listed
in T
able 1-1
is required
for the
adjustments.
Using the
program,
the
computer
controls
the
4263B and
the other
pieces of
equipment to
obtain the
adjustment
data,
and
stores
the
data in
the 4263B
internal EEPROM,
A2U1.
The
adjustment
program
runs
on
the
computer
listed
in T
able 1-1
.The
program
should
be
installed
into
your

item.
At
the end
of each
adjustment, the

calibration values if necessary
.
Signal
Source Level
Adjustment
obtains
the data to adjust the actual signal source output voltage to the
set value
. This adjustment should be performed if any performance test
fails.
Impedance
Measurement 0m
Adjustment
obtains the data to adjust the actual measurement impedance to the
standards' value, when no test leads are used. This adjustment should be
performed if the performance test, Impedance Measurement Accuracy
Test, fails.
Perform the Signal Source Level Adjustment prior to this
adjustment.
