Chapter6 Harmonic Function

This chapter describes the characteristics and operations of the voltage
harmonic measurement function of IT7600 series source.
The bandwidth of IT7600 series AC source is 5kHZ. The voltage/current
harmonic measurement of high speed and wide dynamic scope can be realized.
In the harmonic mode, phase and voltage/current harmonic distortion factor
(UTHD) can be tested.In addition, IT7600 can be used for measuring multiple
harmonics. In addition, multiple harmonic measurements under different frequency
bands can be realized in IT7600. For example, 50 times at 50Hz-500Hz; 20 times at
501Hz-2000Hz; and 10 times at 2001Hz-5000Hz.
IT7600 series source can display harmonic parameters in the list or bar chart
form to make the analysis of test result clear.
Press [Harmonic] on the front panel and the following initial interface of
harmonic measurement will appear.
