Product-Specific Commands—Description
:INPut[1..n]:ATTenuation
Description This command sets the absolute attenuation to a
specific value. The valid range of values depends
on the type of instrument and the current
wavelength. This value is used only when the
ATTenuation control mode is active.
In POWer mode, the device adjusts the
attenuation automatically to match the desired
output power. For this reason, changes made to
attenuation via the INPut[1..n]:ATT command are
not taken into account.
At *RST, the absolute attenuation value that will
be set depends on the instrument you have.
