17 :FUNCtion Commands
:FUNCtion:REFerence
(see page 782)
Command Syntax
:FUNCtion:REFerence <level>
<level> ::= the current reference level in NR3 format.
The :FUNCtion:REFerence command sets the voltage or vertical value represented
at center screen for the selected function. The range of legal values is generally
+/-10 times the current scale of the selected function, but will vary by function. If
you set the reference level to a value outside of the legal range, the level is
automatically set to the nearest legal value.
Query Syntax
:FUNCtion:REFerence?
The :FUNCtion:REFerence? query outputs the current reference level value for the
selected function.
Return Format
<level><NL>
<level> ::= the current reference level in NR3 format.
See Also • "Introduction to :FUNCtion Commands" on page 289
• ":FUNCtion:OFFSet" on page 300
• ":FUNCtion:RANGe" on page 303
• ":FUNCtion:SCALe" on page 305
NOTE
The FUNCtion:REFerence command is equivalent to the :FUNCtion:OFFSet command.
