FPT 
Remarks 
When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default. 
Return Format 
The query returns FPT, TOP, CENTER, BOTTOM; or returns the user-defined idle level position in integer. 
Example 
[:SOURce[<n>]]:BURSt:IDLE FPT      /*Sets the idle level position of the burst mode of CH1 to 1st Point.*/ 
[:SOURce[<n>]]:BURSt:IDLE? /*Queries the idle level position of the burst mode of CH1 and the 
query returns FPT.*/

Syntax 
[:SOURce[<n>]]:FREQuency:CENTer {<frequency>|MINimum|MAXimum} 
[:SOURce[<n>]]:FREQuency:CENTer? [MINimum|MAXimum] 
Description

Remarks   
  You can set the sweep boundaries via the center frequency and frequency span 
(
[:SOURce[<n>]]:FREQuency:SPAN). Different sweep waveforms correspond to different center 
frequency and frequency span ranges. Besides, the center frequency and frequency span are mutually 
affected. Define the minimum frequency of the currently selected waveform
min
F
, the maximum 
frequency as 
max
F
 and 
2/)(
maxmin
FFF
m
