:REFerence <n> Commands
:REFerence <n>
Command syntax:
:FREQuency:REFerence <n>
Specify reference for FREQ
Command parameter:
<n> =
0 to 1.0e6 Reference for FREQ
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:
:FREQuency:REFerence:STATe <b>
Control reference for FREQ
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.
