:EXPonent <name>
:FORMat:EXPonent <name> Set exponent format.
Parameters <name> = NORMal Normal format
= HPRecision High-precision format
Query :EXPonent? Query exponent format
Description This command defines the exponent format. The default setting is NORMal, in which case the
returned value is formatted according to the engineering units of the present range (for example,
0.0012341E+03 on the 2k, 20k, or 200k range). Choosing HPRecision selects the highest preci-
sion possible, so the above example would be returned as 1.2341234E+00 with three extra digits
of precision.
Programming example OUTPUT 716; “:form:exp hpr”
4.17 :OUTPut subsystem
The OUTPut subsystem is used to set polarities for the digital output port. Commands in this
subsystem are summarized in Table 4-10.
:LSENse <name>
:OUTPut:TTL[1]:LSENse <name> Set polarity of line #1
:OUTPut:TTL2:LSENse <name> Set polarity of line #2
:OUTPut:TTL3:LSENse <name> Set polarity of line #3
:OUTPut:TTL4:LSENse <name> Set polarity of line #4
Parameters <name> = AHIGh Set polarity of specified line to active high.

Notes:
1. Brackets [ ] are used to denote optional character sets. These optional characters do not have to be included in the pro-
gram message. Do not use brackets [ ] in the program message.
2. Angle brackets < > are used to indicate parameter type. Do not use angle brackets < > in the program message.
3. Upper case characters indicate the short-form version for each command word.
