SWEPT FREQUENCY ACCURACY (Cont'd)
7.
Refer to
Table
4-8, press the HP
8340B/41B [START FREQ]
key and enter the start frequency shown in
Table 4-8. Press the
[STOP
FREQ] key and enter the appropriate stop frequency. Press the
[SWEEP TIME]
key and enter the appropriate sweep time. Select the appropriate spectrum analyzer resolution bandwidth.
Set the spectrum analyzer center frequency to the appropriate frequency for the percentage of band being
tested. Press the HP 8340B/41B [CONT]
key to return to the swept mode. Stop Frequencies greater than
20.0 GHz only apply to the HP
8340B.
8.
Ideally, the oscilloscope response will
be at the center graticule
line,
if
not,
adjust the spectrum analyzer
center frequency to
bring the oscilloscope response to the center graticule line. The difference between the
original center frequency
setting and
present center frequency is
the HP 8340B/41B swept frequency
error.
This
error should
be within the test limit
shown in
Table
4-8.
9.
Repeat steps
3
through
8
to test at
50%
and
80%
of band.
NOTE
If
the swept frequency accuracy error exceeds the test
limit,
refer to the Sweep
Gain and Delay Adjustments, in Section V, Adjustments in the Service Manual.
