1. The VirtualBench FGEN can output ±12 Vpp at a maximum frequency of 20 MHz. In this exercise, use the FGEN
to output an AC sine wave with 5 Vpp at 60 Hz with no DC offset voltage. Figure 2.11 shows the FGEN with these
settings configured.

2. Now change the DMM measurement mode from DC Voltage to AC Voltage. This configures the DMM to take
RMS measurements instead of regular averaging. From your simulation, you know that the expected voltage is
around 1.768 Vrms. Therefore, set your DMM to the 10 V range. Figure 2.12 shows the DMM configured for
taking AC voltage measurements in a 10 V range.

3. Enable the FGEN output.
4. Measure the RMS value of the voltage drop (Vrms) of your AC-powered circuit and record it in the field below:
a. Total AC Vrms (measured):_______________________
