FREQUENCY SPAN
The frequency span changes the total display frequency range symmetrically about the center frequency. Note that
the frequency span readout refers to the total display frequency range; to determine frequency span per division,
divide by 10.
As the frequency span is changed, resolution bandwidth and video bandwidth automatically change to provide a
predetermined level of resolution and noise averaging, respectively. Sweep time also changes automatically to
maintain a calibrated display.
The analyzer can be adjusted to span a maximum of 2.5 GHz in the low band and 22 GHz (2 to 24 GHz range) in
the microwave band. A minimum span of 100 Hz is allowed in both bands as well as 0 Hz (zero span) which
enables the analyzer to function as a fixed-tune receiver. In zero span, the analyzer can display modulation
waveforms in the time domain.
DATA Entry with FREQUENCY SPAN
Changes the frequency span continuously.
Changes the frequency span to the next value in a 1, 2,5, 10 sequence.
Enters an exact value up to three digits, depending on span. Additional
digits will be deleted without rounding.
