Chapter 6
Harmonic Measurement Function
This chapter describes the features and use of the harmonic measurement function of the 5335C power meter in
details.
6.1
Basic Concepts
With the 100kHZ bandwidth, the 5335C power meter can realize harmonic measurement of high speed and wide
dynamic range. The voltage, current, active power, reactive power and phase of harmonics and total harmonic
distortion (THD) factor can be tested in the harmonic mode. In addition, the 5335C power meter can be used for
multiple harmonic measurements, 50-order harmonics of the fundamental frequency at most.
The 5335C power meter displays harmonic parameters in the list or bar chart form so as to provide clear analysis of
test results.
Introduction of soft keys on the interface

Introduction of harmonic information
When the “BAR” button is selected in the harmonic measurement interface, the bar chart of harmonic
measurement results will be displayed. The bar chart is used for displaying the percentage of different harmonics.
