1. Connecting to the Signal Source: First, connect the probe to the signal you want to measure. The probe typically has a tip for making contact with the circuit and a ground clip for establishing a reference point. Make sure the ground clip is securely connected to a ground point in your circuit to avoid inaccurate readings or noise.
2. Adjusting the Vertical Scale (Volts/Div): The vertical scale controls how many volts each vertical division on the screen represents. Adjust this setting so that the waveform fits comfortably within the display. If the signal is too small, decrease the Volts/Div to zoom in. If it's too large, increase the Volts/Div to zoom out.
3. Adjusting the Time Base (Time/Div): The time base controls how much time each horizontal division on the screen represents. Adjust this setting to see the waveform's details over time. If the waveform is compressed, decrease the Time/Div to see a shorter time span. If it's stretched out, increase the Time/Div to see a longer time span.
4. Triggering the Oscilloscope: Triggering is crucial for capturing stable waveforms. The trigger tells the oscilloscope when to start displaying the waveform. You can set the trigger to activate on a rising edge, falling edge, or a specific voltage level. Experiment with different trigger settings to find the one that gives you a stable, clear waveform.
5. Capturing the Waveform: Once you have the vertical scale, time base, and trigger settings adjusted, the oscilloscope should display a stable waveform. You can then use the oscilloscope's measurement tools to analyze the waveform. These tools typically include voltage measurements (peak-to-peak, RMS, etc.), time measurements (frequency, period, pulse width, etc.), and more.
6. Using the Measurement Tools: The FNIRSI 1013D usually has built-in measurement tools that automatically calculate various parameters of the waveform. Consult the user manual to learn how to access and use these tools. They can save you a lot of time and effort in analyzing signals.
