SCPI-defined Parameters. In addition to the ANSI/IEEE 488.2-1987-defined
parameters, WCA200A Series support the following SCPI-defined parameters.
H
<NRf> for boolean
OFF | ON | 0 | 1 | <NRf>
You can use <NRf> for boolean parameter. The values other than zero (OFF)
are regarded as one (ON).
H
MAXimum and MINimum for numeric parameters
You can use MAXimum and MINimum for the numeric parameter <NRf>.
The following example sets the trigger level to the maximum (100%).
:TRIGger[:SEQuence]:LEVel:IF MAXimum
The commands that have numeric parameters support the following query:
<header>? { MAXimum | MINimum }
The query command returns the maximum or minimum acceptable value for
the command. For example,
:TRIGger[:SEQuence]:LEVel:IF? MAXimum
returns 100 indicating the maximum trigger level is 100%.
H
UP and DOWN for numeric parameters
The [:SENse]:FREQuency:CENTer command (refer to page 2--429) supports
UP and DOWN for the numeric parameters. The increment/decrement of
UP/DOWN is determined by one of these commands:
[:SENse]:FREQuency:CENTer:STEP:AUTO
[:SENse]:FREQuency:CENTer:STEP[:INCRement]
