| | | Generate Square waves | 6. In the Signal Generator Math Function tab, set frequency to 500kHz, and type in the function box 4*sin(t) + 4*sin(3*t)/3 + 4*sin(5*t)/5 + 4*sin(7*t)/7 + 4*sin(9*t)/9 + 4*sin(11*t)/11 (you can copy and paste the text to Scopy) and click apply.

Refer to the Step resource image for reference| |
| | |Waveform Phase – Seconds| 1. Open Waveform tab. Set frequency to 500Hz. Set Phase to 90 degrees. Then change phase unit to seconds. | {{ :university:tools:m2k:scopy:test-cases: signal_generator-additional_feature_phase_step1.png?100 |}}| The value of Phase should automatically change to 500us that is 90 degrees in seconds for a frequency of 500Hz. | |
| | |:::| 2. Increase and decrease the value of phase.| | The display should follow accordingly.| |
| | |::: | 3. Increase phase value to 1.5 ms. Then change again the unit to degrees.| {{ :university:tools:m2k:scopy:test-cases: signal_generator-additional_feature_phase_step3.png?100 |}} | The value should now be 270 degrees. | |
| | |:::| 4. Change frequency to 1 MHz. Then set phase to 1us. This corresponds to a full period of a 1MHz frequency. | {{ :university:tools:m2k:scopy:test-cases: signal_generator-additional_feature_phase_step4.png?100 |}}| The interface should look like in steps resources picture.| |
| | |:::| 5. Change phase unit to degrees. |{{ :university:tools:m2k:scopy:test-cases: signal_generator-additional_feature_phase_step5.png?100 |}} | The value should be 360 degrees. | |
