Sweep Time
Used to calculate the power in the reference channel. Sweep Time can be set
manually or put into Auto mode.
For instruments with non-sweeping acquisitions, such as VXT, the time value is the
acquisition time for an individual FFT segment, not the cumulated time for all FFT
segments in the channel.
