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!
## 5
TODO fill calculated values
TODO Note that we intend to use the ideal, not the measured, values for calculated RMS)
| Set Mag. | Set Freq. | Read magnitude | Read period | Calculated Freq. | Calculated RMS | Measured RMS |
| 2V | 100 Hz | 2.10 V | 9.994 ms | XXXXXHz | .....V | 1.4236 V |
| 2V | 50 kHz | 2.05 V | 19.947 us | | | 1.4112 V |
| 5V | 100 Hz | 5.11 V | 10.007 ms | | | 3.5522 V |
| 5V | 50 kHz | 5.11 V | 20.005 us | | | 3.5451 V |
## 6
TODO divide
| Read magnitude | Measured RMS | Mag. div. by RMS |
| 2.10 V | 1.4236 V | |
| 2.05 V | 1.4112 V | |
| 5.11 V | 3.5522 V | |
| 5.11 V | 3.5451 V | |
## 7
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.
TODO fill calculated values
NOTE You can calculate V_rms from $$sqrt((Vdc)^2 + (Vm/sqrt(2))^2)$$
| Set Mag. | Set Freq. | DC off | Read magnitude | Read period | Calculated Freq. | Calculated RMS | Measured RMS |
| 2V | 100 Hz | 2V | 2.13 V | 10.001 ms | .....Hz | .....V | 2.44 V |
| 2V | 100 Hz | -5V | 2.11 V | 9.996 ms | | | 5.19 V |
| 5V | 100 Hz | 2V | 10.3/2V | 9.998 ms | | | 4.05 V |
| 5V | 100 Hz | -5V | 10.4/2V | 9.997 ms | | | 6.16 V |
## 9
Using Table 5, check how your measured and calculated RMS values compare.
TODO copy values and divide
| Read magnitude | Measured RMS | Mag. div. by RMS |
| 2.10 V | 1.4236 V | |
| 2.05 V | 1.4112 V | |
| 5.11 V | 3.5522 V | |
| 5.11 V | 3.5451 V | |

| Set Mag. | Set Freq. | Duty | Read magnitude | Read period | Calculated Freq. | Calculated RMS | Measured RMS |
| 2V | 100 Hz | 25% | 4.22/2 V | 10.000ms | .....Hz | .....V | 2.02 V |
| 2V | 100 Hz | 50% | 4.26/2 V | 10.000ms | | | 2.01 V |
| 5V | 100 Hz | 25% | 10.4/2 V | 9.998ms | | | 5.04 V |
