 PSLAB contains many instruments like oscilloscope, multimeter, logical analyzer and many more. One of them is the wave generator. Wave generator is the module which can produce different waveforms having desired properties through the PSLAB hardware device. In this video I will demonstrate how to produce sine waves and square waves using the wave generator module. First we need to connect the PSLAB hardware device to the Android smartphone with the PSLAB app installed on it. For this we need an OTG wire and a Type B USB cable. So for connecting first we will connect the Type B USB cable to the PSLAB hardware device. Then we will connect the USB cable to the OTG wire. Then we will connect this OTG wire to the smartphone. As you can see a dialog box appears. This dialog box prompts the user to open the PSLAB when the USB device is connected. As we click OK in the dialog box it will open the PSLAB Android app and the USB connected icon on the top right shows that the PSLAB device has been connected. We can also view it in the device screen. Here it is showing that device connected successfully and below is the version of the PSLAB hardware device. For producing sine waves we need a connecting wire. Then we will connect the Wave1 pin here which is used by wave generator to produce analog waveforms and we will connect it to the CH1 channel here which is used by the oscilloscope to observe the produced waveform. Now in the PSLAB Android app we will open the wave generator module. As you can see this is the UI of the wave generator module. The monitor and the panel on the left side is used for controlling waveforms like sine wave and triangular wave and the panel and the monitor on the right side are used for controlling digital waves like square wave and PWM signal. So for producing the sine wave first we will click on the Wave1 pin then we will click on the sine button then we have to set the frequency for which we will click on the frequency button. For setting the frequency we will use the C-ig bar and then press set. Now the frequency has been set. For viewing it we will click on the view button. Now we will choose the oscilloscope instrument. As in the PSLAB device we have connected it to the CH1 channel so we will select the CH1 channel. As you can see the sine wave is produced on the oscilloscope. Now similarly for producing square waves we will connect the square one pin here to the channel one pin here which is used by the oscilloscope. Now in wave generator we will click on SQR1 button then we will set it frequency by clicking on frequency button set then we have to set its duty cycle. We will set it to 50% that is 0.5. Now for viewing the square wave click on the view button then we will choose the oscilloscope. And again we will click on the CH1 channel and we can view the square wave. So this is how we can produce different waveforms using wave generator module in the PSLAB Android app through the PSLAB hardware device. Thank you.
