460 Agilent N8201A Performance Downconverter Synthetic Instrument Module, 250 kHz to 26.5 GHz
23 Sweep
Sweep Time
Selects the length of time in which the N8201A sweeps the displayed frequency span. In
swept spans, the sweep time varies from 1 millisecond to 2000 seconds plus time for setup
which is not calculated as part of the sweep time. Reducing the sweep time increases the
rate of sweeps. In zero span, the sweep time may be set from 1 μs to 6000 s. In FFT spans,
the sweep time is not controlled by the user, but is an estimate of the time required to make
FFT measurements. Sweep time is coupled to RBW and VBW, so changing those
parameters may change the sweep time. When the N8201A has been set to FFT (that is,
Auto Couple > FFT & Sweep > Manual), Sweep Time, and Auto Sweep Time are unavailable
(grayed out).
You may select a sweep time less than the auto-coupled value; however this may generate
measurement errors. If this happens, the error message: Meas Uncal will appear in the
upper right corner of the display.
In zero span or FFT sweeps, the auto/manual function of this key is not applicable. When
Sweep Time (Auto) is selected in non-zero span, any changes to Sweep Time while in zero
span will revert to the Auto value when you return to non-zero span. When Sweep Time
(Man) is selected in non-zero span, any changes to Sweep Time while in zero span will be
maintained when you return to non-zero span (within the available sweep time range).
When entering zero span from a non-zero span, the sweep time does not change.
