c) Press Output1 or tap the channel output configuration status bar
to turn on the output of CH1 in the channel setting interface.
5. Record the reading of the multimeter and judge whether it is within the
specification ("Amplitude Output Value (Vrms)" in Table 2-1) range.
6. Keep the output impedance of CH1 of DG2000 at 50Ω and the output waveform
of CH1 as a sine waveform with 1kHz frequency and 0V
dc
offset. Set the output
amplitude of CH1 to 100mVpp, 500mVpp, 1Vpp, 5Vpp and 10Vpp respectively.
Record the readings of the multimeter respectively and judge whether the
readings are within the specification (“Amplitude Output Value (Vrms)” in Table
2-1) range.

10Vpp ±105mVpp 9.895Vpp to 10.105Vpp 3.5Vrms to 3.5732Vrms
Note
[1]
: "Allowed Error" is calculated from the specification "±(1% of setting value) ±5mVpp".
Note
[2]
: "Amplitude Output Value (Vrms)" is calculated from "Amplitude Output Value (Vpp)".
The conversion relation between Vrms and Vpp is
rms22pp VV =

7. Repeat Step 1-6 to test the AC amplitude accuracy of CH2 and record the test
results.
