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
nd
and 4
th
harmonics from the [CH1] connector (Harmonic 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
nd
and 4
th
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
nd
and 4
th
orders of harmonics are output.
Note: the actual harmonics output is determined by the “Order” and “Type”
currently specified.
