Measurement Results
The values shown in the measurement menu Modulation can be divided into three groups:
•
Setting values
•
Scalar measurement results (single values)
•
Arrays (the measurement curve plotted as a function of time)
The values are indicated in a parameter line, the test diagram and a tabular overview below:

parameter
line
The second parameter line contains the following marker values:
Level and time of reference marker
Level and time of delta marker 1 (setting absolute ) or difference
from reference marker (setting relative )
Level and time of delta marker 2 (setting absolute ) or difference
from reference marker (setting relative )
Remote control
The settings are retrieved using the query corresponding to the setting command
