ST1952 Operation Manual
54
Command parameter:
<n> = -757.5 to 757.5
Reference for ACV
-1010 to 1010 Reference for DCV
DEFault 0 (All measurement functions)
MINimum Mininum value for specified function
MAXimum Maximum value for specified function
Query:
:REFerence?
Query reference for relative function
Descripton:
These commands are used to establish a reference value for the specified function. When reference
is enabled (: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) eatablishes 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:ACQuiry command, the:REFerence? Query
command returns the acquired reference value.
:STATe <b>
Command syntax:
:VOLTage:AC:REFerence:STATe <b>
Control reference for ACV
:VOLTage:DC:REFerence:STATe <b>
Control reference for DCV
Command parameter:
<b> = 1 or ON
Enable reference
0 or OFF
Disable reference
Query:
:STATe?
Query state of reference.
Description:
These commands are used to enable or disable Reference for the specified function. When enabled,
the displayed reading will include the programmed reference value. When disabled, the displayed
reading will not include the reference value.
:ACQuire
Command syntax:
:VOLTage:AC:REFerence:ACQuire
Acquire reference for ACV
