combined with the existing average. Exponential averaging weights new data more
than old data, which facilitates tracking of slow-changing signals. The average will be
displayed at the end of each sweep.
•Repeat—When you set Avg Mode to Repeat, after reaching the average count, all
previous result data is cleared and the average count is set back to 1.

2.13.3 Harmonics Harmonics indicates the number of harmonics to measure before computing the total
harmonic distortion. The minimum number is 2 (only the fundamental and second
harmonic will be measured). The maximum number is 10.

2.13.4 ST/Harmonic Sets the sweep time used to measure each harmonic. The value is set to 200 divided by the
resolution bandwidth, or 10 ms, whichever is greater when the measurement is started.
This sweep time is used only for measuring harmonics. The analyzer sweep time before the
