Linear Frequency Sweep (Hz)

The ~~~~~~ softkey activates a linear frequency sweep that is displayed on a standard
graticule with ten equal horizontal divisions. This is the preset default sweep type.
For a linear sweep, sweep time is combined with the channel's frequency span to compute a
source sweep rate:
sweep rate = (frequency span) / (sweep time)
Since the sweep time may be affected by various factors, the equation provided here is merely
an indication of the ideal (fastest) sweep rate. If the user-specified sweep time is greater
than 15 ms times the number of points, the sweep changes from a continuous ramp sweep
to a stepped CW sweep. Also, for 10 Hz or 30 Hz IF bandwidths, the sweep is automatically
converted to a stepped CW sweep.
In the linear frequency sweep mode it is possible, with Option 010, to transform the data for
time domain measurements using the inverse Fourier transform technique.
