Harmonic Distortion Test
Specification:
Sine Wave Spectrum Purity
Harmonic Distortion
Typical (0dBm)
DC to 10MHz (include 10MHz): <-65dBc
10MHz to 30MHz (include 30MHz): <-55dBc
30MHz to 60MHz (include 60MHz): <-50dBc
Test Procedures:
1. Make sure that the environment temperature is between 18℃ and 28℃ and
DG1000Z has been warmed up for at least 30 minutes. Connect the channel
output terminal (take CH1 as an example; the test method is also applicable to
CH2) of DG1000Z with the signal input terminal of the spectrum analyzer using a
dual-BNC connecting cable and N-BNC adaptor as shown in Figure 2-4.

2. Turn on DG1000Z. Press Utility Set To Default OK to restore DG1000Z
to the factory setting.
3. Set DG1000Z:
a) Set the output impedance of CH1 to 50Ω (press Utility Channel Set
Output Set Imped and select “Load”).
b) Set the output waveform of CH1 to a sine waveform with 10MHz frequency,
0dBm amplitude and 0V
DC
offset.
c) Press Output1 to turn on the output of CH1.
