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 Emis-
sions measurements is described in
chapter 11.5.7.6, "Programming Example: Spuri-
5.7.3.2
Limit Lines in Spurious Measurements
Limit lines allow you to check the measured data against specified limit values. Gener-
ally, it is possible to define limit lines for any measurement in the Spectrum application
using the LINES key. For Spurious measurements, however, a special limit line is
available via the "Sweep List", and it is strongly recommended that you use only this
limit line definition.
In the "Sweep List" you can define a limit line that varies its level according to the
specified frequency ranges. A distinguished limit line is automatically defined according
to the current "Sweep List" settings every time the settings change. This limit line is
labeled "_SPURIOUS_LINE_ABS_<xxx>", where <xxx> is an index to distinguish limit
lines between different measurement channels.
If a limit check is activated in the "Sweep List", the "_SPURIOUS_LINE_ABS" limit line
is indicated by a red line in the display, and the result of the limit check is indicated at
the top of the diagram. Note that only "Pass" or "Fail" is indicated; a "margin" function
as for general limit lines is not available. Also, only absolute limits can be checked, not
relative ones.
As for general limit lines, the results of each limit line check are displayed (here:
"_SPURIOUS_LINE_ABS"), as well as the combined result for all defined limit lines
("Limit Check").
