Discrete Parameters. Use discrete parameters to program settings
that have a finite number of values. Discrete parameters use
mnemonics to represent each valid setting. They have a long and a
short form, like command mnemonics. You can use mixed upper and
lower case letters for discrete parameters.
Examples of discrete parameters:
INTernal
level internally
DIODe
level using an external diode
PMETer
level using an external power meter
MMHead
level using a mm-wave source module
Examples of discrete parameters in commands:
100 OUTPUT @Source
;
‘I
:POWer:ALC:SOURce
INT”
110 OUTPUT @Source
;
”
:POWer:ALC:SOURce
mmh”
Although discrete parameters values look like command keywords,
do not confuse the two. In particular, be sure to use colons and
spaces properly. Use a colon to separate command mnemonics from
each other. Use a space to separate parameters from command
mnemonics.
Boolean Parameters. Boolean parameters represent a single binary
condition that is either true or false. There are only four possible
values for a Boolean parameter.
Examples of Boolean parameters:
ON
Boolean TRUE, upper/lower case allowed
OFF
Boolean FALSE, upper/lower case allowed
1
Boolean TRUE
0
Boolean FALSE
Examples of Boolean parameters in commands:
100 OUTPUT @Source ;
”
: FM :
STATe
On”
110 OUTPUT
OSource;“:AM:STATe
1”
