Using the Oscilloscope¶
What is an oscilloscope¶
An instrument used to measure voltage changes over a period of time in real time.
How to use it¶
- Connect SI1 and SI2 pins on PSLab board to CH1 and CH2 pins respectively for Analog mode or connect SQ1,SQ2,SQ3 pins to CH1, CH2, CH3 pins respectively for Digital mode.
- Go to Wave Generator instrument in the PSLab Android application.
- Select either Digital or Analog mode.
- Set desired frequency, phase and duty(in case of Digital mode) values for Wave1 and Wave2 (Analog mode) or SQ1,SQ2,SQ3 (Digital mode).
- Exit from Wave Generator instrument and got to Oscilloscope instrument in PSLab Android application.
- Select either or all from the CH1, CH2, CH3 checkbox to see waves generated at each channel.
- Change timebase of the waves from the Trigger and Timebase section on the left control panel.
- Plot waves against each other from the XY-Plot section on the left control panel.
- View results of Fourier transform or curve fitting from the Data Analysis section on the left control panel.
- Use in built microphone of the smartphone as input select IN-BUILT MIC option on the bottom panel on the main screen.
- Use record button to record currently generated waves and store the data in a CSV file and play it back at will.
In the desktop app you will see something like this:
