Note
[1]
: The range is from 1 ms to 4,000 s in non-zero span.
Sweep Time Mode
Sets the "Sweep Time" to be "Auto" or "Manual". By default, it is "Auto".
Remarks:
In non-zero span mode, the analyzer selects the shortest sweep time based on
the current RBW and VBW settings if "Auto" is selected.
Decreasing the sweep time can speed up the measurement. However, an error
may be caused if the set sweep time is less than the minimum sweep time in
Auto coupling. At this point, "UNCAL" is shown in the status bar on the screen.
In zero span mode, the Sweep Time Mode menu is disabled and grayed out.
When the system exits the zero span mode, the auto sweep coupling mode will
restore to its previous state.
When RBW is smaller than 1 kHz, the spectrum analyzer starts to perform FFT
sweeps. At this time, the Sweep Time menu is disabled and grayed out.
Sweep Time Rule
Sets the sweep type to "Norm" or "Accy". The sweep will be faster if "Norm" is
selected; while in "Accy" type, a higher measurement precision can be obtained.
When RBW is smaller than 1 kHz, the spectrum analyzer starts to perform FFT
sweeps. At this time, the Sweep Time menu is disabled and grayed out.
Continue
Sets the sweep mode to be continuous.
Remarks:
If the instrument is in single sweep mode and no measurement function is
enabled, press this key to enter continuous sweep mode. In this case, if the
trigger conditions are met, the instrument will sweep continuously.
If the instrument is in single sweep mode and the measurement function is
