Product-Specific Commands—Description
:OUTPut[1..n]:RPOWer
Description This command sets the relative power to a
specific value. The valid range of values depends
on the type of instrument, the configuration, and
the input power. This value is used only when the
POWer control mode is active.
At *RST, the value that will be set depends on the
instrument you have.
Syntax :OUTPut[1..n]:RPOWer<wsp><RelativePower[
<wsp>DBM]>|MAXimum|MINimum|DEFault
Parameter(s) RelativePower:
The program data syntax for <RelativePower> is
defined as a <numeric_value> element
followed by an optional <SUFFIX PROGRAM
DATA> element. The allowed <SUFFIX
PROGRAM DATA> element is DBM. The
<RelativePower> special forms MINimum,
MAXimum and DEFault are accepted on input.
MINimum allows to set the instrument to the
lowest supported value.
MAXimum allows to set the instrument to the
highest supported value.
DEFault allows the instrument to select a value
for the <RelativePower> parameter.
The <RelativePower> parameter corresponds to
a valid relative power. You can use the
OUTPut[1..n]:RPOWer? MAX and
OUTPut[1..n]:RPOWer? MIN queries to
determine a valid range for the power.
