"User"
Limits are checked according to the values in a user-defined file. For
details on the required file format, see Chapter 5.3.6.1, "Limit File
Format", on page 134.
If a user-defined limit file is loaded for harmonics measurement, only
the results for the specified harmonics are calculated, displayed, and
exported. A limit check is performed only for those harmonics for
which a limit value is defined.
If "User" is selected, the "Loaded File" field indicates the currently loa-
ded file.
Select the file that contains the user-defined limits using the Open
function.
Remote command:
HARMonic:LIMits:TYPE on page 322
Open
Opens a user-defined file that contains the selection of harmonics and, optionally, the
limits for individual harmonics.
The "Loaded File" field indicates the currently loaded file.
Note that this setting is only available if Limits is set to "User".
Remote command:
HARMonic:LIMits:NAME on page 322
HARMonic:LIMits:LOAD on page 321
HARMonic:RESult<m>:NOHarmonics? on page 329
HARMonic:FUNDamental:CURRent? on page 320
Display Harmonics, Max No Harmonics
Determines the number of harmonics to be displayed in the bargraph. Up to 64 har-
monics can be displayed. By decreasing the number of harmonics, the bargraph
becomes easier to analyze.
Note that this setting only affects the graphical result display. It has no effect on the
measurement results or the selection of harmonics for which results are provided dur-
ing a file export (manually or via remote command). For that purpose, see Limits.
Harmonics that were previously eliminated by the Limits setting cannot be displayed.
To restrict the number of harmonics to display, select a predefined selection, or "User"
and enter the "Max No Harmonics". All harmonics of an order smaller than or equal to
the specified value (and selected for analysis) are displayed.
Remote command:
HARMonic:DISPlay:TYPE on page 319
HARMonic:DISPlay:USER on page 320
HARMonic:RESult<m>:NOHarmonics? on page 329
Average
Determines the number of acquisitions for which the results are averaged. By default,
no averaging is performed.
Note that invalid measurements (for example due to clipping or a missing fundamental
frequency) are not considered for averaging.
