Examples of extended numeric parameters:

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, just like command mnemonics. You can use mixed

upper and lower case letters for discrete parameters.

Examples of discrete parameters used with the TRIG:SOURce subsystem:

Although discrete parameter 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.

Examples of discrete parameters in commands:

100 OUTPUT @Source;"TRIGger:SOURce BUS"

100 OUTPUT @Source;"TRIGger:SOURce IMMediate"

100 OUTPUT @Source;"TRIGger:SOURce EXTernal"
