# Part 1
|
|
Set the function generator to the values lined out in Table 1. Using
|
|
the oscilloscope read of the requested data to confirm that you set
|
|
the function generator correctly. Calculate the frequency and RMS from
|
|
your oscilloscope readings. Use the DMM to record the RMS
|
|
voltage. (Watch out for the “high Z” setting!

|
|
Using Table 3, check how your measured and calculated RMS values compare.
|
|
|

## 8
|
|
Set the function generator to the values lined out in Table 4. Using
|
|
the oscilloscope read of the requested data to confirm that you set
|
|
the function generator correctly. Calculate the frequency and RMS from
|
|
your oscilloscope readings (note that here you will have to use eq. 1!
|
|
I suggest doing a general case first, then substitute specific values
|
|
at the end). Use the DMM to record the RMS voltage.

NOTE You can calculate V_rms from $$sqrt((Vdc)^2 + (Vm/sqrt(2))^2)$$
