CALCulate:DELTamarker<m>:FUNCtion:FMEasurement:LIMit<k>:DELTa?
This command queries the vertical distance from the deltamarker position to the limit
line. The unit is dB.
If the deltamarker has been assigned to a different trace than the limit line, or if no limit
ine is defined for the marker position, the command returns -200.
Return values:
<Amplitude>
Vertical distance to the limit line in dB.
Example:
CALC:DELT3:FUNC:FME:LIM2:DELT?
Queries the distance of deltamarker 3 to the second limit line.
Usage:
Query only

Programming Example: EMI Measurement
This example demonstrates how to detect electromagnetic interferences (EMI) in a
remote environment.
