Test Procedures
1. Make sure that the environment temperature is between 18℃ and 28℃ and
DG2000 has been warmed up for at least 30 minutes. Connect the 50Ω load to
the channel output terminal (take CH1 as an example; the test method is also
applicable to CH2) of DG2000; connect the 50Ω load and the voltage input
terminals of the digital multimeter using a BNC-Dual banana plug connecting
cable as shown in Figure 2-2.

2. Turn on the multimeter, select the ACV measurement function and set the range
to “Auto”.
3. Turn on DG2000. When the Shift key is illuminated, press Sine/Preset and
tap the Def icon, then a dialog box is displayed, tap "Apply" to restore DG2000
to the factory setting.
4. Set DG2000:
a) Set the output impedance of CH1 to 50Ω. (Tap the channel output
configuration status bar
under the user interface to enter the
channel setting interface. Tap the OutputSet  HighZ to select "Off". Tap
the Impedance menu label, and set the impedance to 50Ω.)
b) Set the output waveform of CH1 to a sine waveform with 1kHz frequency,
20mVpp amplitude and 0V
dc
offset.
