Figure 31 Frequency Selection Dialog
Single Frequency —
Allows selection of a single frequency, when a frequency is entered using this option, any
previously selected frequencies are removed from the Selected Frequencies list
Fundamental Groups —
Drop-down menu contains the fundamentals available for selection.
Fundamental —
Select from the list of fundamental frequencies derived from the fundamental group selected.
Note:
Select all other options for the fundamental before adding it to the list of selected frequencies.
Options include harmonic selection, intermod selection, and tolerance settings.
H1 through H5 —
Select harmonics reported for the fundamental.
F2 Frequency —
Select another fundamental from the list to use as the “F2” frequency in an intermodulation
product.
Note:
The F2 frequency must have already been added to the selected frequencies list.
Note:
An intermod is a combination of two frequencies in the form: IMD = F1+nF2, where n is one of {-
3,-2,-1,1,2,3}.
Intermod —
Select the number of intermodulation products reported for the fundamental. Up to 6 IMD products
can be selected for a fundamental (3 pairs):
F1 +1/-1 F2 (2 IMD products).
F1 +2/-2 F2 (4 IMD products).
F1 +3/-3 F2 (6 IMD products).
Tolerance —
The Tolerance field defines the tracking filter window as a percentage from the center of the
fundamental frequency. This gives the frequency range of a generator for a frequency.
Detection Filter —
Filter Width is used to widen or narrow the measurement filters.
