2. Set fundamental waveform parameters: In this example, various
parameters of the fundamental waveform take the default values. You can also
refer to descriptions in "To Output Basic Waveform" to set various
fundamental waveform parameters such as frequency/period, amplitude/high
level, offset/low level, and start phase.
3. Enable harmonic function: Press the Shift key and its backlight turns on.
Press Home/Menu on the front panel, and then the waveform selection
interface is displayed. Tap Continuous and then select the "Harm" icon to go
to the harmonic parameter setting interface automatically.
4. Set harmonic count: In the harmonic parameter setting interface, tap the
Count parameter input field to input a value 5 with pop-up numeric keypad. Tap
"Ok".
5. Select the harmonic type: In the harmonic parameter setting interface, tap
the Type parameter selection field to select the desired even harmonic.
6. Set harmonic amplitude: In the harmonic parameter setting menu, set the
amplitude of 2th and 4th orders of harmonic.
1)
Tap the No. parameter input field to input 2 with the pop-up numeric
keypad, and then tap "Ok".
2) Tap the Harm Ampl parameter input field to input 2 with the pop-up
numeric keypad, select the unit "Vpp". Then tap "Ok".
3) Refer to Step 1 and Step 2 to set the amplitude of the 4th order harmonic to
1 Vpp.
7. Set harmonic phase: In the harmonic parameter setting menu, set the phases
of 2th and 4th orders of harmonic in sequence.
1)
Tap the No. parameter input field to input 2 with the pop-up numeric
keypad, and then tap "Ok".
2)
Tap the Harm Phase parameter input field to input 30 with the pop-up
numeric keypad, select the unit "°". Then tap "Ok".
3)
Refer to Step 1 and Step 2 to set the phase of the 4th order harmonic to
50°.
8. Enable channel output: Press Output1, and the backlight turns on. Also,
you can tap the channel output configuration status bar
the channel output. Then, the channel status is highlighted (i.g.
and the fundamental waveform, 2th and 4th order of harmonics are output from
the [CH1] connector based on the current configurations.
9. Observe the output waveform: Connect the [CH1] connector of DG2000 to
the oscilloscope by using the BNC cable. The waveform is as shown in the figure
below.
