Programming
Making Measurements
Always force the Keysight 86120B to wait for non-sequential commands
The Keysight 86120B normally processes its remote programming commands
sequentially. The instrument waits until the actions specified by a particular com-
mand are completely finished before reading and executing the next command.
However, there are a few non-sequential commands where this is not true. Non-
sequential commands do
not finish executing before the next command is inter-
preted.
The following is a list of the Keysight 86120B’s non-sequential commands:
:CALCulate1:TRANsform:FREQuency:POINTs
:CALCulate2:PEXCursion
:CALCulate2:PTHReshold
:CALCulate2:WLIMit:STATe
:CALCulate2:WLIMit:STARt:FREQuency
:CALCulate2:WLIMit:STARt:WAVelength
:CALCulate2:WLIMit:STARt:WNUMber
:CALCulate2:WLIMit:STOP:FREQuency
:CALCulate2:WLIMit:STOP:WAVelength
:CALCulate2:WLIMit:STOP:WNUMber
:CALCulate3:SNR:AUTO
:SENSe:CORRection:ELEVation
:INITiate:CONTinuous
:INITiate[:IMMediate]
The following additional commands are also non-sequential commands if CALCu-
late3:SNR:AUTO is set to OFF:
:CALCulate3:REFerence:FREQuency
:CALCulate3:REFerence:WAVelength
:CALCulate3:REFerence:WNUMber
The benefit of non-sequential commands is that, in some situations, they can reduce
the overall execution times of programs. For example, you can set the peak excur-
sion, peak threshold, and elevation and use a *WAI command at the end to save
ARRay and the SCPI standard
According to the SCPI command reference, ARRay command causes an instru-
ment to take multiple measurements. (A <size> parameter indicates the number
of measurements to take.) However, the Keysight 86120B’s ARRay command
refers to the measurements performed for one measurement sweep; this results
in an array of measured signals. Because the <size> parameter does not apply,
any <size> parameter sent will be ignored by the instrument. No syntax error
will be generated if a <size> parameter is sent.
