Input/Output

Input/Output

The Input/Output features are common across multiple Modes and Measurements. These common
features are described in this section. See the Measurement description for information on
features that are unique.

The Input/Output key accesses the keys that control the Input/Output parameters of the
instrument.  In general, these are functions associated with external connections to the analyzer,
either to the inputs or the outputs.  Since these connections tend to be fairly stable within a given
setup, in general, the input/output settings do not change when you Preset the analyzer.

Other functions related to the input/output connections, but which tend to change on a
measurement by measurement basis, can be found under the Trigger and AMPTD Y Scale keys. In
addition, some of the digital I/O bus configurations can be found under the System key.

The functions in the Input/Output menu are "global" (common) to all Modes (applications). But
individual Input/Output functions only appear in a Mode if they apply to that Mode.  Functions that apply
to a Mode but not to all measurements in the Mode may be grayed-out in some measurements.

The Input Port selection is the first menu under the Input/Output key:

Remote Command

[:SENSe]:FEED RF|AIQ|EMIXer

[:SENSe]:FEED?

Example

:FEED RF

:FEED?

Couplings

The [:SENSe]:FEED RF command turns the calibrator OFF

Preset

This setting is unaffected by a Preset or power cycle. It survives a Mode Preset and mode
changes.

It is set to RF on a "Restore Input/Output Defaults" or "Restore System Defaults->All"

Compatibility SCPI

[:SENSe]:FEED AREFerence

In the PSA the calibrator was one of the inputs and selected using the AREF parameter to the
same :FEED command that switched the inputs.  In the X-Series it is controlled in a separate
menu and overrides the input selection.  For code compatibility the [:SENSe]:FEED AREFerence
command is provided, and is aliased to [SENSe]:FEED:AREF REF50, which causes the input to be
switched to the 50 MHz calibrator.  The [:SENSe]:FEED RF command switches the input back to
the RF port and turns the calibrator OFF, thus providing full compatibility with the PSA calibrator
function.

Note that after sending this, the query [:SENSe]:FEED? does not return “AREF” but instead the
