Push to navigate to the Waveform Menu. If necessary, push until the top level
softkeys are shown. See Figure 4-11. Select Edit Harmonics, Fluctuating
Harmonics, Interharmonics Flicker or Dip by pressing the appropriate softkey.

4-26. Harmonics, DC and Sine
The following sections explain the Harmonics, dc, and Sine Menus.
4-27. Definition
A Harmonic is an integer multiple of the fundamental frequency. In the 6100B, harmonic
number 1 is the fundamental frequency. DC is denoted by harmonic 0.
4-28. Access to Edit Harmonics
Use to navigate to the Waveform menu and select Edit Harmonics from the
softkeys.
4-29. 6100B Capability
Harmonics 2
nd
to 100th up to 6 kHz
Simultaneous Harmonics 99 (excluding dc and the 1st)
Max. Amplitude of a Single Harmonic The maximum value for a harmonic < 2850 Hz is 30 % of
range. (See Chapter 1 for the profile above 2850 Hz)
Current channel bandwidth setting 1.5 kHz or 6 kHz (1.5 kHz or 3 kHz for high current options
if fitted)
Note
Selecting the lower bandwidth setting reduces the number of harmonics that
can be set but increases inductive drive capability.
4-30. Sine/Harmonic Mode
Pushing the Enable/Disable Waveshape softkey toggles between Sine and
Harmonics mode.
Note
The Output Menu will show either “Sine” or “Harmonic”.
In Sine mode only Range, RMS and Angle fields can be edited. The one exception is the
voltage channel of L1 where the phase angle is fixed at 0.000 degrees. Select the required
entry field using the softkeys or .
DC is not available in Sine mode.
Figure 4-12 below shows the Harmonic mode with time domain waveform selected. The
same set up is shown in Figure 4-13 but here the frequency domain representation of the
signal is shown.
