Input/Output - Agilent Technologies X Series Manual

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 softkeys 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
digital I/O bus configurations can be found under the
The functions in the Input/Output menu are "global" (common) to all Modes
NOTE
(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.

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

The calibrator was one of the inputs in legacy analyzers but is outside the
input selection in the X-Series. The legacy parameter [:SENSe]:FEED
AREFerence is aliased to the new command [:SENSe]:FEED:AREF REF50
for backwards compatibility. This causes the input to be switched to the 50
MHz calibrator, but after sending this, the query [:SENSe]:FEED? will NOT
return "AREF" but instead the currently selected input.
