•Fast
Activates the fast sweep mode.
Fast sweep mode provides a fast measurement
function that decreases the sweep time. However,
this mode brings a decrease of amplitude accuracy.
Key access: [BW/SWP] > {Sweep} > {Sweep Mode}
Single Sweep
When the analyzer is in continuous sweep mode
and not in a measurement mode ([MEAS] > Measure
Off), pressing [BW/SWP] > {Single Sweep} convert the
continuous sweep to single sweep and executes a
sweep after the trigger condition is met. If the
analyzer is already in single sweep, pressing
[BW/SWP] > {Single Sweep} executes a new sweep as
soon as the trigger condition is met.
If Average is on ([TRACE] > {More (1 of 2)} > {Average}
> On), pressing [BW/SWP] > {Single Sweep} halts
averaging of the current value, and continue
averaging from the current count number as soon
as a single sweep function triggers.
Key access: [BW/SWP] > {Sweep}
NOTE
Fast sweep is valid only when span is no less than 50 MHz.
Measurement data is not ganruanteed in fast sweep mode.
