Parameters <n> = -3.1 to 3.1 Reference for ACI and DCI

-757.5 to 757.5 Reference for ACV

-1010 to 1010 Reference for DCV

-10.1 to 10.1 Reference for DCV for sense terminals

0 to 120e6 Reference for Ω2 and Ω4

0 to 1.5e7 Reference for FREQ

0 to 1 Reference for PER

-200 to 1372 Reference for TEMP

DEFault 0 (all functions)

MINimum Minimum value for speciﬁed function

MAXimum Maximum value for speciﬁed function

Query :REFerence? Query programmed reference value

:REFerence? DEFault Query *RST default reference value

:REFerence? MINimum Query lowest allowable reference value

:REFerence? MAXimum Query largest allowable reference value

Description These commands are used to establish a reference value for the speciﬁed

function. When Reference is enabled (see :REFerence:STATe), the result will

be the algebraic difference between the input signal and the reference value:

Reading = Input signal - Reference

From the front panel, reference is called relative (REL).

The :REFerence <n> command is coupled to the :ACQuire command. The

last command sent (:REFerence <n> or :ACQuire) establishes the reference.

When a reference is set using the :REFerence <n> command, the

:REFerence? query command returns the programmed value. Conversely,

when a reference is set using the :ACQuire command, the :REFerence? query

command returns the acquired reference value.
