CF Step
Key access: [FREQ] > {CF Step}
Changes the step size for the center frequency
function. Once a step size has been selected and
the center frequency function is activated, the
arrow keys change the center frequency by the
step- size value. The step size function is useful for
finding harmonics and sidebands beyond the
current frequency span of the analyzer. When
auto- coupled, the center size is set to one division
(10 percent of the span).
Freq Offset
Key access: [FREQ] > {Freq Offset}
Allows you to input a frequency offset value that is
added to the frequency readout of the marker, to
account for frequency conversions external to the
analyzer. Offset entries are added to all frequency
readouts including marker, start frequency, and
stop frequency. Offsets are not added to the span
or frequency count readouts. Entering an offset
does not affect the trace display.
