Product-Specific Commands—Description
:INPut[1..n]:OFFSet
Description This command sets an offset value for the
attenuation. This offset value will be added to the
absolute attenuation. The same offset value will
be used for all wavelengths. This value is used
only when the ATTenuation control mode is
active. The offset is only taken into account when
the INPut[1..n]:RATTenuation command is used.
At *RST, the current value is set to 0 dB.
Syntax :INPut[1..n]:OFFSet<wsp><Offset[<wsp>DB]
>|MAXimum|MINimum|DEFault
Parameter(s) Offset:
The program data syntax for <Offset> is defined
as a <numeric_value> element followed by an
optional <SUFFIX PROGRAM DATA> element.
The allowed <SUFFIX PROGRAM DATA>
element is DB. The <Offset> special forms
MINimum, MAXimum and DEFault are accepted
on input.
MINimum allows to set the instrument to the
smallest supported value.
MAXimum allows to set the instrument to the
highest supported value.
DEFault allows the instrument to select a value
for the <Offset> parameter.
The <Offset> parameter corresponds to a valid
offset value. You can use the INPut[1..n]:OFFSet?
MAX and INPut[1..n]:OFFSet? MIN queries to
determine a valid range for the attenuation
offset.
