[:SOURce]:PO W er:A TT enuation
Attenuator
Syntax [:SOURce ]:POWer:ATTenuation <wsp>
<value>j MINj DEFj MAX
Description This command sets the level of attenuation of
an inbuilt optional attenuator , if this is installed.
The specied range for the attenuation is
0.00dB to 40.00dB . Y ou can set to the minimum,
default or maximum programmable values by
sending MIN , DEF , or MAX , respectively , instead
of the value .
The resolution of the attenuation is specied
to be 0.1dB . The actual resolution of the
attenuator is better than this (typically 0.04dB).
T o allow you access to this resolution, you can
specify the attenuation to two decimal places
with the HP-IB command.
Y ou need to be in the Attenuation Mode (see
\[:SOURce]:POW er:A TT enuation:A UTO")
for this value to have an aect. The
output power is a combination of
this value and the laser output power (see
\[:SOURce]:POW er[:LEV el][:IMMediate][:AMPlitude]").
In this respect, this command does not conrm
to the SCPI standard. The SCPI standard
requires that entering an explicit value for the
attenuation switches the attenuation mode OFF .
The default units are DB .
