6-6 Remote Control PLZ-U
6.3.2 Parameter Format
The parameter format of SCPI is derived from the program parameter format
defined in IEEE 488.2.
SCPI parameter format
Boolean parameters
A Boolean parameter expresses a 1 or 0 condition or an ON or OFF condition.
A Boolean parameter can take on four values, 1, 0, ON, or OFF.
Below is an example of a set command using a Boolean parameter.
Set command: [SOURce:]FUNCtion:CTIMe {OFF|ON}
Discrete parameters
A discrete parameter is used when only a limited number of values are available for
the program setting.
Like the SCPI commands, discrete parameters have a long form and a short form.
Responses are returned in the short form.
Below is an example of a set command using a discrete parameter.
Set command: [SOURce:]POWer:RANGe
{LOW|MEDium|HIGH}
Numeric parameters
A numeric parameter is a numeric representation consisting of a decimal point,
optional sign, measurement unit, symbol, etc.
If DEFault is available as a parameter, the device automatically selects the default
value.
Units such as V, A, and W can also be used with the numeric parameter.
If a value that cannot be assigned is entered, the device rounds the value to the clos-
est possible value.
Below is an example of a command using a numeric parameter.
Set command: CURRent {<current>|MIN|MAX}
