±(1% of setting value) ±5mV
Test Procedures
1. Make sure that the environment temperature is between 18℃ and 28℃ and
DG800 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 DG800; 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 DG800. Press Preset and tap the Def icon, then a dialog box is
displayed, tap "Apply" to restore DG800 to the factory setting.
4. Set DG800:
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.
c) Press Output1 or tap the channel output configuration status bar
