To Output Harmonics

DG1000Z can be used as a harmonic generator to output harmonic with specified

order, amplitude and phase. This section introduces how to output the 2

and 4

harmonics from the [CH1] connector (Amplitude: 2Vpp and 1Vpp, Phase: 30° and

50°, Order: 5).

1. To select output channel

Press CH1|CH2 to select CH1. Now the boarder of the channel status bar is
displayed in yellow.

2. To set the parameters of the fundamental waveform

Set the frequency/period, amplitude/high level, offset/low level and start phase

of the fundamental waveform according to “To Output Basic Waveform”.

3. To enable the harmonic function

Press Sine



Harm to select “On”. Press Harmonic Para to enter the

harmonic setting menu.

4. To set harmonic order

Press Order in the harmonic setting menu, use the numeric keyboard to input 5

and press Sure.

 The range is limited by the maximum output frequency of the instrument as

well as the fundamental waveform frequency.

 Range: integers within 2 to maximum output frequency of the

instrument ÷ fundamental waveform frequency. The maximum is 8.

5. To select harmonic type

Press Type in the harmonic setting menu to select Even or User.

Method 1: Even

Press this key and the instrument would output fundamental waveform and

even harmonics (the 2

and 4

harmonics).

Method 2: User

Press this key and the instrument would output the user-defined orders of

harmonics. The highest order is 8.

8 bits binary data is used to represent the output status of the 8 orders of

harmonics respectively, wherein, 1 represents enabling the output of the

corresponding harmonic and 0 represents disabling the output of the

corresponding harmonic. Users only need to use the numeric keyboard to

modify the value of each data bit (note: the leftmost bit representing

fundamental waveform is always X and cannot be modified). For example, set

the 8 bits data to X101 0000, thus 2

and 4

orders of harmonics are output.

Note: the actual harmonics output is determined by the “Order” and “Type”

currently specified.
