You can also send engineering unit suffixes (V, A, or SEC)
with numeric parameters. If only specific numeric values are
accepted, the power supply will automatically round the
input numeric parameters. The following command uses a
numeric parameter:
CURR {<current>|MIN|MAX|UP|DOWN}
Discrete parameters
Discrete parameters are used to program settings that have a
limited number of values such as BUS and IMM. Query
responses will always return the short form in all
upper- case letters. The following command uses discrete
parameters:
TRIG:SOUR {BUS|IMM}
Boolean parameters
Boolean parameters represent a single binary condition that
is either true or false. For a false condition, the power
supply will accept OFF or 0. For a true condition, the power
supply will accept ON or 1. When you query a boolean
setting, the power supply will always return 0 or 1. The
following command uses a boolean parameter:
DISP {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:
DISP:TEXT <quoted string>
