4 Input/Output Functions
Input/Output
[:SENSe]:FEED QONLy aliases to [:SENSe]:FEED:IQ:TYPE QONLy
The query [:SENSe]:FEED? will always returns AIQ whatever the type of legacy parameters IQ | IONLy
| QONLy has been used.

Notes
Most of the settings in the X-Series Input/Output system, including External Gain, Amplitude
Corrections settings and data, etc., are shared by all modes and are not changed by a mode switch.
Furthermore, most variables in the Input/Output system key are not affected by Mode Preset. Both of
these behaviors represent a departure from legacy behavior.
In the X-Series. Input/Output settings are reset by using the "Restore Input/Output Defaults"
function. They can also be reset to their default values through the System->Restore System
Defaults-> In/Out Config key or through the System ->Restore System Defaults -> All key (and
corresponding SCPI).
While this matches most use cases better, it does create some code compatibility issues. For
example, Amplitude Corrections are no longer turned off by a Mode Preset, but instead by using the
"Restore Input/Output Defaults" key/SCPI.
Although Input/Output settings are not part of each Mode’s State, they are saved in the Save State
files, so that all of the instrument settings can be recalled with Recall State, as in legacy
instruments.

Remote Command
:INPut:MIXer EXTernal|INTernal
:INPut:MIXer?
Example INP:MIX INT
INP:MIX?
Notes In legacy analyzers you choose between the Internal mixer or an External Mixer. In the X-Series, the
External Mixer is one of the choices for the Input and is selected using the FEED command
(:SENSe:FEED EXTMixer).
For compatibility, the INPut:MIXer EXTernal|INTernal legacy command is mapped as follows:
1. When INPut:MIXer EXTernal is received, SENSe:FEED EMIXer is executed.
2. When INPut:MIXer INTernal is received, SENSe:FEED RF is executed.
3. When INPut:MIXer? is received, the response will be INT if any input other than the external mixer
is selected and EXT if the external mixer is selected
Preset INT

Notes
PSA supports the following SCPI Command :
:INPut:MIXer:TYPE PRESelected|UNPReselect
:INPut:MIXer:TYPE?
PXA does not support the :INPut:MIXer:TYPE command.
Initial S/W Revision A.08.01
Input/Output variables - Preset behavior
Virtually all the input/output settings are NOT a part of mode preset. They can be set to their default value
