6.4.1 Data Source
Lets you select the input to the analysis engine. The following options are available:
Input
INPut
A hardware input signal (the default). This causes the measurement to take its input
data from the hardware input (for example RF, I/Q, or EXTMixer) currently selected on
the Input tab under Input/Output
Capture
Buffer
STORed
Data stored in a storage buffer from a single earlier acquisition. Selecting "Capture
Buffer" allows you to use data that has been previously stored using the "Current Meas
-> Capture Buffer" control. You can make a measurement and then, if you want to
make a different measurement using the exact same data, store the raw data using the
"Current Meas -> Capture Buffer" control and select “Capture Buffer” as the Data
Source, then switch to the other measurement. You must have previously done a
"Current Meas -> Capture Buffer" before the Capture Buffer choice is available for use
Recorded
RECorded
Data recorded to memory from a set of earlier acquisitions. Selecting “Recorded” lets
you use the record buffer, previously filled by using the “Recording” tab in the Sweep
menu, as the input (only available in the Pulse measurement)
File
FILE
Data recorded on a storage device from a set of earlier acquisitions. If you load a
Recording using Recording under the Recall key, “File” is automatically selected, which
lets you use the recorded data as though it were coming from the Input
See "Data Source" on page 2406 for a table of available choices on a per-
measurement basis.
Remote Command
[:SENSe]:FEED:DATA INPut | STORed | RECorded | FILE
[:SENSe]:FEED:DATA?
Example Cause the measurement to look at the input selection:
:FEED:DATA INP
Cause stored measurement data to be used with a different measurement that supports this:
:FEED:DATA STOR
Dependencies If you switch to a measurement that does not support the currently selected Data Source, the
instrument switches Data Source to "Input". Attempting to select an unavailable Data Source via SCPI
generates an error
The Data Source setting is independent for each mode. Not all Data Sources are available in all modes
Preset Unaffected by Preset, but set to INPut by Restore Input/Output Defaults or Restore System
Defaults->All
State Saved Saved in instrument state
