6 SCPI Basics

Extended Numeric Parameters

Most subsystems use extended numeric parameters to specify physical quantities.

Extended numeric parameters accept all numeric parameter values and other special values

as well.

The following are examples of extended numeric parameters:

Discrete Parameters

Discrete parameters use mnemonics to represent each valid setting. They have a long and a

short form, just like command mnemonics. You can mix upper and lower case letters for

discrete parameters.

The following examples of discrete parameters are used with the command

:TRIGger[:SEQuence]:SOURce BUS|IMMediate|EXTernal.

Although discrete parameters look like command keywords, do not confuse the two. In

particular, be sure to use colons and spaces correctly. Use a colon to separate command

mnemonics from each other and a space to separate parameters from command

mnemonics.

.5 digits left of decimal point optional

Extended Numeric Parameters Special Parameters

100 any simple numeric value DEFault resets parameter to its default value

1.2GHZ GHZ can be used for exponential (E009) UP increments the parameter

200MHZ MHZ can be used for exponential (E006) DOWN decrements the parameter

−100mV negative 100 millivolts MINimum sets parameter to smallest possible

value

10DEG 10 degrees MAXimum sets parameter to largest possible

value

BUS LAN triggering

IMMediate immediate trigger (free run)

EXTernal external triggering
