CENTER FREQUENCY
CENTER FREQUENCY
The center frequency can be tuned continuously from 0 to 22 GHz using any combination of DATA controls.
Additional band overlap enables the center frequency to tune up to 24 GHz and below to - 1 GHz.
The center frequency can be set with 1 Hz resolution. Readout resolution is 1% of the frequency span, hence the
highest readout resolution is obtained with narrow frequency spans. Data entered, however, is always accurate to
1 Hz even though the center frequency readout may display less resolution.
During band crossings (from 0 - 2.5 GHz low band to 2 - 22 GHz microwave band) or at band edges (below 0 Hz
or above 22 GHz), the frequency span may change to enable the desired center frequency to be set. (See
Appendix for detailed information.)

20 Manual Operation
Changes the center frequency by about one half the total frequency span
each full turn.
Changes the center frequency by one tenth of the frequency span, i.e., by
one division. COUPLED FUNCTION ['::::'I can be used to change this step
size.
Allows direct center frequency entry. The analyzer will accept a center fre-
quency entry with 1 Hz resolution. Even though the readout may show a
