<Amplitude>
This command queries the vertical distance from the marker position to the limit line.
The unit is dB.
If the marker 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.
Suffix:
<n>

<m>
<li>
1..n
Return values:
<Amplitude>
Vertical distance to the limit line in dB.
Example:
CALC:MARK3:FUNC:FME:LIM2:LDEL?
Queries the distance of marker 3 to the second limit line.
Usage:
Query only

Evaluating the results
The commands required to control the demodulation of signals at the marker position
are described in
Chapter 12.8.3.14, "Marker demodulation"
12.5.13.8
Programming example: EMI measurement
This example demonstrates how to detect electromagnetic interferences (EMI) in a
remote environment.
