Discrete Parameters
Discrete parameters are used to program settings that have a
limited number of values (like BUS, IMMediate, EXTernal). They have a short form and a
long form just like command keywords. You can mix upper- and lower-case letters.
Query responses will always return the short form in all upper-case letters. The following
command uses discrete parameters:
TRIGger:SOURce {BUS|IMMediate|EXTernal}
Boolean Parameters
Boolean parameters represent a single binary condition that is
either true or false. For a false condition, the multimeter will accept “OFF” or “0”. For a
true condition, the multimeter will accept “ON” or “1”. When you query a boolean setting,
the instrument will always return “0” or “1”. The following command uses a boolean
parameter:
INPut:IMPedance:AUTO {OFF|ON}
String Parameters
String parameters can contain virtually any set of ASCII characters.
A string must begin and end with matching quotes; either with a single quote or with a
double quote. You can include the quote delimiter as part of the string by typing it twice
without any characters in between. The following command uses a string parameter:
DISPlay:TEXT <quoted string>
