b) Set the output waveform of CH1 to a sine waveform with 1kHz frequency,
20mVpp amplitude and 0V
DC
offset.
c) Press Output1 to turn on the output of CH1.
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 DG1000Z 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 ±101mVpp 9.899Vpp to 10.101Vpp 3.5Vrms to 3.5717Vrms
Note
[1]
: “Allowed Error” is calculated from the specification “±1% of setting value ±1mVpp”.
Note
[2]
: “Amplitude Output Value (Vrms)” is calculated from “Amplitude Output Value (Vpp)”.
The conversion relation between Vrms and Vpp is

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