PROCEDURE
Determine Cal Factor Status
Determine the status of the calibration factors and enter new calibration factors if necessary. Connect
the power sensor
or
sensor module to the Modulation Analyzer’s SENSOR input. (The power sensor
cable need not be connected to the source at this time.)
1.
Select RF POWER. If Error
15
is
displayed, no calibration factors have been entered. Enter
calibration factors as described in steps a and b below. If Error
15
is
not displayed, proceed
to step
4.
2.
Enter the reference cal factor (the reference cal factor
is
the cal factor for
50
MHz; all other cal
factors are relative to it):
37.3
SPCL, reference cal factor value (printed on
a
label on the power sensor),
96
CAL FACTOR (Blue Key, MHz).
Example: Enter a reference cal factor of
98.5%
into the Automatic Cal Factor table.

3.
Enter each frequency/cal-factor pair:
37.3
SPCL, frequency value (in MHz), cal-factor value, %CAL FACTOR (Blue Key, MHz).
Repeat this step until all frequency/cal-factor pairs have been entered.
0
Disregard Error
15
if it is displayed during cal factor entry.
0
If an error is made during entry of any value, select CLEAR and immediately re-enter the
correct value.
Example: Enter a cal factor of
99.0%
at a frequency of
1
MHz.
