: 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
