[:SOURce]:POWer[:LEVel][:IMMediate][:AMPlitude]
Syntax [ :SOURce ] :POWer [ :LEVel ][ :IMMediate ][ :AMPlitude ] < wsp >
< value > j MIN j DEF j MAX
Description This command sets the power of the laser output.
The specied range for the amplitude is -10dBm to -4dBm,
or 100  W to 398  W.You can set to the minimum, default or
maximum programmable values by sending MIN , DEF ,or MAX ,
respectively, instead of the value.
Attenuator
If you have the optional attenuator installed, the range is
-50dBm to -5.5dBm, or 10nW to 300  W.
If you are using the Attenuation Mode (see
\[:SOURce]:POWer:ATTenuation:AUTO"), then this
value sets the laser output power, which is not the same as the
output power. The output power is a combination of this value
and the attenuation (see \[:SOURce]:POWer:ATTenuation").
The values for the output power that you set in the Power
Mode, and the laser output power that you set in the
Attenuation Mode, are stored and used independently.
Note
The instrument may not be able to output a signal
with the maximum programmable power, it will
output a signal with the maximum power. Use the
[:SOURce]:POWer[:LEVel][:IMMediate][:AMPlitude]? query to
nd out the power being output.
The default units are DBM ,or W , depending on the unit selected
by the [ :SOURce ] :POWer:UNIT command. Independently of the
chosen default unit, you can also specify the unit to be used as
DBM , DBMW , PW , NW , UW , MW or W .

Description This query returns the amplitude level of the output power. The
value returned is the actual amplitude that is output, which
