4 Input/Output Functions
Input/Output
Inputs
Sets the measurement to use the input selections (RF, AREF, I/Q)
Key Path
Input/Output, Data Source
Example
FEED:DATA INP causes the measurement to look at the input selection
Notes
Does not auto return.
Readback
Inputs
Initial S/W Revision
Prior to A.02.00
Capture Buffer
Some WCDMA and demod measurements support this feature. This allows sharing of the raw data across
certain measurements. If you want to make another measurement on the same signal, you would store
that raw data using the "Current Meas -> Capture Buffer" key. Then the data is available for the next
measurement to use. You must have raw data stored in the instrument memory before the Capture Buffer
choice is available for use.
Key Path
Input/Output, Data Source
Example
FEED:DATA STOR causes stored measurement data to be used with a different measurement that
supports this.
Notes
Does not auto return. This key is grayed out when you switch to a measurement that does not
support this feature.
Dependencies
If you switch to a measurement that does not support this feature, then the instrument switches to
use "Inputs" and grays out this key. If the grayed out key is pressed, it generates a message.
Readback
Stored Data
Initial S/W Revision
Prior to A.02.00
Current Meas -> Capture Buffer
Pressing this key stores the raw data of one measurement in the internal memory of the instrument where
it can then be used by a different measurement by pressing "Stored Data". When raw data is stored, then
the data source selection switch automatically changes to "Stored Data". Stored raw data cannot be
directly accessed by a user. There is no save/recall function to save the raw data in an external media.
However if you want to get the stored raw data, you must first perform a measurement using the stored
raw data. Now you can access the used raw data, which is the same as stored raw data, using the FETch or
READ commands.
