4. Record the reading of the DMM and check if the reading exceeds the range listed
in the Limit of Actual Output Amplitude (Vrms) in Table 2-1.
5. Keep other settings of DG4000 unchanged, set the amplitude to 100 mVpp, 500
mVpp, 1 Vpp, 5 Vpp and 10 Vpp respectively, record the readings of the DMM
and check if the readings exceed the ranges listed in the Limit of Actual Output
Amplitude (Vrms) in Table 2-1.

Note
[1]
: “Permitted Error” is calculated from the specification “±1% of setting ±2 mVpp”.
Note
[2]
: “Limit of Actual Output Amplitude (Vrms)” is calculated from “Limit of Actual Output Amplitude (Vpp)”.
The relation between Vrms and Vpp is
