[FFT Width Auto Man]
● Menu description: to set FFT Width. The FFT width includes [Auto], [<100kHz], [<3 MHz], [<13
MHz], [<=Max.]. FFT width is only active when the FFT sweep type is selected. Under Auto type, when
the signal/spectrum analyzer performs FFT spectrum measurement, the maximum resolution bandwidth
is 30kHz. To guarantee best dynamic measurement range, the signal/spectrum analyzer automatically
optimizes the FFT width within 100kHz. The larger is the FFT width, the faster is FFT spectrum
measurement, but the dynamic range performance will be affected.
Under FFT sweep, the FFT width setup limits the maximum value for center frequency step of each tune.
For example, if [<100Hz] is selected, the maximum value for center freq step of each tune is 100Hz. As
the FFT width gets larger, the count of instrument center frequencies get smaller when performing
measurement of same frequency scope, and the response measurement gets faster. Therefore, to improve
measurement speed, you can manually change the FFT width.

key on the front panel has no corresponding soft menu. This function
is mainly used for manual trigger of a sweep. When the Average is ON, this function performs the
sweeps at the count specified by the Average Count.
In remote control programming and system establishment, this function combined with *WAI can
effectively synchronize the sweep process and enable the trace data obtained after the *WAI finishes
directly correspond to the sweep process one by one.
