Defining ranges by remote control
In Spurious Emissions measurements, there are no remote commands to insert new
ranges between existing ranges directly. However, you can delete or re-define the
existing ranges to create the required order.
A remote command example for defining parameters and ranges in spurious emissions
measurements can be found in chapter 7 "Remote Control – Programming Examples"
of the Operating manual.
Result Evaluation
In addition to the graphical results of the spurious measurement displayed in the dia-
gram, a result table can be displayed to evaluate the limit check results (see also
"Working with Limit Lines in Spurious Measurements" on page 286). Which data is dis-
played in the evaluation list can be defined in the "List Evaluation" menu (see "List
Evaluation" on page 292).
The following information is provided in the evaluation list:
Column Description
Range Low Frequency range start for range the peak value
belongs to
Range Up Frequency range stop for range the peak value
belongs to
RBW RBW of the range
Frequency Frequency at the peak value
Power Abs Absolute power level at the peak value
ΔLimit Deviation of the absolute power level from the
defined limit for the peak value
By default, one peak per range is displayed. However, you can change the settings to:
●
Display all peaks ("Details ON")
●
Display a certain number of peaks per range ("Details ON" + "Peaks per Range")
●
Display only peaks that exceed a threshold ("Margin")
In addition to listing the peaks in the list evaluation, detected peaks can be indicated by
blue squares in the diagram ("Show Peaks").
