3 VMA Mode
3.4 IQ Waveform Measurement
The Marker Function menu controls which marker functions are turned on, and
allows you to adjust the setup parameters for each function. These parameters
include the following, but only one parameter can be assigned to a given marker:
–
Marker Noise
–
Interval Power
–
Interval Density
–
Off
More Information
In the Waveform measurement, post-processing operations on markers are based
on the measurement specifications. Marker Functions are distinct from
measurement functions, which automatically perform complex sequences of setup,
data acquisition, and display operations, to measure specified signal characteristics.
Marker Functions are specified for each individual marker, and may be turned on
individually for each marker.
Marker Time
This is the fundamental control that you use to move a marker around on the trace.
It is the same as "Marker Time" on page 745 in Settings.
Interval Function
Sets the marker control function type to one of:
Option Parameter
Marker Noise
NOISe
Interval Power
BPOWer
Interval Density
BDENsity
Marker Function Off
OFF
All interactions and dependencies detailed under the control description are
enforced when the remote command is sent.
