Chapter 4 Harmonic Output

The HDG3000B(C) can be used as a harmonic generator to output harmonic with specified order,

amplitude and phase. It is usually used in the test of harmonic detector device or harmonic filter

device.

This chapter introduces how to configure the generator to output harmonics. Subjects in this

chapter:



Overview



Set the Basic Waveform Parameters



Set the Harmonic Order



Select the Harmonic Type


