3.9 Spectral Flatness Measurement
Next Pk Right
Pressing Next Pk Right moves the selected marker to the nearest peak right of the
current marker that meets all enabled peak criteria. If there is no valid peak to the
right of the current marker position, a “No peak found” message is generated and
the marker is not moved.
If the selected marker was off, then it is turned on as a normal marker and a peak
search is performed.
Remote Command
:CALCulate:FLATness:MARKer[1]|2|...|12:MAXimum:RIGHt
Example
:CALC:FLATness:MARK2:MAX:RIGH
Notes Sending this command selects the subopcoded marker.
State Saved Not Saved in instrument state
Next Pk Left
Pressing Next Pk Left moves the selected marker to the nearest peak left of the
current marker that meets all enabled peak criteria. If there is no valid peak to the
left of the current marker position, a “No peak found” message is generated and the
marker is not moved.
If the selected marker was off, then it is turned on as a normal marker and a peak
search is performed.
In the Code Domain measurement in WCDMA, pressing this control moves the
selected marker to the nearest active channel left of the current marker when
Marker Trace is either Code Domain Power or Code Domain Error. In other cases,
moves the selected marker to the highest peak left of the current marker.
In the Mod Accuracy measurement in WCDMA, pressing this control moves the
selected marker to the nearest active channel left of the current marker when
Marker Trace is Code Domain Power. In other cases, moves the selected marker to
the highest peak left of the current marker.
In LTE/LTE-Advanced modulation analysis measurements, if the format is complex
(vector or constellation), the marker moves back in time to the next peak. A valid
peak is one for which the displayed Y-axis values drop monotonically on both sides
of the local maximum at least 4% of the distance between the top and bottom of the
display grid before the values begin to rise again.
