Basic Measurements with iOscilloscope

Okay, let's get down to business and learn how to make some basic measurements with your iOscilloscope. Measuring signals accurately is the heart of using an oscilloscope, so mastering these techniques is crucial. We'll cover frequency, amplitude, and pulse width measurements, providing you with a solid foundation for more advanced analysis.

Frequency Measurement: Frequency is the number of cycles a signal completes per second, measured in Hertz (Hz). To measure the frequency of a signal with an iOscilloscope, follow these steps:

Connect the probe to the signal you want to measure.
Adjust the timebase (seconds per division) until you can see at least one complete cycle of the waveform on the screen.
Use the measurement tools in the app to measure the period (T) of the waveform. The period is the time it takes for one complete cycle.
Calculate the frequency (f) using the formula: f = 1 / T.

Many iOscilloscope apps have an automatic frequency measurement feature that will display the frequency directly on the screen. This is a huge time-saver!

Amplitude Measurement: Amplitude is the maximum voltage of a signal, measured in volts (V). To measure the amplitude of a signal, follow these steps:

Connect the probe to the signal you want to measure.
Adjust the voltage scale (volts per division) until the waveform fills most of the screen vertically.
Use the measurement tools in the app to measure the peak-to-peak voltage (Vpp) of the waveform. The peak-to-peak voltage is the difference between the maximum and minimum voltage values.
Calculate the amplitude (A) by dividing the peak-to-peak voltage by 2: A = Vpp / 2. Alternatively, some apps directly measure the amplitude or RMS voltage.

Pulse Width Measurement: Pulse width is the duration of a pulse, measured in seconds (s). To measure the pulse width of a signal, follow these steps:

Connect the probe to the signal you want to measure.
Adjust the timebase (seconds per division) until you can clearly see the pulse on the screen.
Use the measurement tools in the app to measure the time between the rising edge and the falling edge of the pulse. This is the pulse width.

Some iOscilloscope apps have an automatic pulse width measurement feature that will display the pulse width directly on the screen.
