REFERENCE
REF_POSITION | REFPO
Command /Query
DESCRIPTION
The REF_POSITION command sets the
vertical offset of the current reference
channel. This command is only used when
the current reference channel has been
saved, and the display state is on.
The REF_POSITION? query returns the
vertical offset of the current reference
channel.
COMMAND SYNTAX
REF_ POSITION <offset>
<offset>:= vertical offset value with unit.
Note:
• If there is no unit(V/mV/uV) added, it
defaults to be V.
• The range of legal offset varies with the
value set by the REFSC command. If you
set the offset to a value outside of the legal
range, the offset value is automatically set
to the nearest legal value.
QUERY SYNTAX
REF_ POSITION?
RESPONSE FORMAT
REF_ POSITION <offset>
<offset>:= Numerical value in E-notation
with SI unit.
EXAMPLE
When the Reference function is on, REFB
has been saved and the scale is 2 V, the
following command sets the current
reference channel vertical offset to 0.2 V.
Command message:
REFPO 0.2V
