Instrument Default Setup
When you press the PRESET key, the R&S FSH is set to its default setup or presets. It is best to select
the PRESET when you are going to perform a new measurement task. The new settings can then be
made on the basis of the more familiar default setup without the old settings affecting the measurement.
Operating sequence:
 Press the PRESET key (green key below and to the right of the rotary knob).
The R&S FSH is immediately set to the default setup.
Setting the Frequency
The R&S FSH's frequency is set with the FREQ key. The frequency can be specified in terms of the
center frequency (center freq. = frequency at the center of the frequency axis in the measurement
diagram) or the start and stop frequency for a particular span.
It is best to enter the center frequency when a signal is to be measured at a known frequency. When
you are investigating signals, e.g. harmonics, that are within a particular frequency range, the best
option is entering a start and stop frequency to define the span.
