Key Entry
Data Type
:DIGital:DIAGnostic:LOOPback
Supported N5172B/82B with option 003 or 004 or both
:DIGital:DIAGnostic:LOOPback? DIGBus|CABLe|N5102A|DEVice
This command selects and executes a loop back test that validates the integrity of digital data.
DIGBus This choice selects a loop back test on the Digital Bus connector at the signal
generator side.
CABLe This choice selects a loop back test using the Digital Bus Loop Back Fixture test
board.
N5102A This choice selects a loop back test for the N5102A module.
DEVice This choice selects a loop back test using the LOOP BACK TEST SINGLE ENDED
IO DUAL 40 PIN board.
Example
:DIG:DIAG:LOOP? DEV
The preceding example runs the diagnostic test on the Single Ended IO Dual 40 Pin device and
returns a pass or fail condition.
