Discrete Parameters: A discrete parameter is used
to set up a discrete number of parameters (e.g.,
NORMal, EARTh, NLIne). Like command key
words, either short or long, and upper or lower
case letters can be used. Query returns always
return short form upper case letters. The command
below uses discrete parameters:
CONFogure:CURRent{ACDC|DC|AC|ACPeak}
Boolean Parameters: Boolean parameters represent
a true or false binary condition. A false condition is
represented by, “OFF” or “0” whilst “ON” or “1”
is used for a true condition. The instrument will
return “0” or “1” from a Boolean query. Below is
an example of a command with Boolean
parameters.
CONFigure:AUTO {OFF|ON}
String Parameters: String parameters include almost
all the ASCII characters. A character must end and
start with a single or double quotation mark.
Quotation delimiters can also be used in a string
when quotation marks are used within quotation
marks. For example:
“”quote””  “quote”.
