Introduction to Programming
Signal Generation – The SOURce Subsystem
If you have the optical attenuator installed, the range is specified in
the Specifications in the appropriate User's Guide.
If you are using the Attenuation Mode (see
[:SOURce[n]][:CHANnel[n]]:POWer:ATTenuation:AUTO on
page 102), 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[n]][:CHANnel[n]]:POWer:ATTenuation on page 101).
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.
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
find out the power being output
MIN: minimum programmable value
MAX: maximum programmable value
DEF: This is not the preset (*RST) default value, but is
half the sum of the minimum programmable value
and the maximum programmable level
