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:
Extended numeric parameters also include the following special 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 properly. Use a colon to separate command mnemonics from each
other and a space to separate parameters from command mnemonics.
The following are examples of discrete parameters in commands:
100
any simple numeric value
1.2GHz
GHz can be used for exponential (E009)
200MHz
MHz can be used for exponential (E006)
100mV
negative 100 millivolts
10DEG
10 degrees
DEFault
resets the parameter to its default value
UP
increments the parameter
DOWN
decrements the parameter
MINimum
sets the parameter to the smallest possible value
MAXimum
sets the parameter to the largest possible value
BUS
GPIB, LAN, or USB triggering
IMMediate
immediate trigger (free run)
EXTernal
external triggering
TRIGger:SOURce BUS
TRIGger:SOURce IMMediate
TRIGger:SOURce EXTernal
