Experiment 2: Measuring Signal Timing and Frequency

Objective: Learn how to measure timing and frequency of signals using a logic analyzer or oscilloscope for analyzing digital and analog systems.

Steps:

1. Connect the Signal Source to the Measurement Device:
   • Identify the signal line you want to measure.
   • Connect the input probes of the logic analyzer or oscilloscope to the signal line.
   • Ensure a proper ground connection for accurate measurements.
2. Set Up the Device to Trigger on Edges:
   • Open the configuration menu of the measurement device.
   • Select the desired trigger condition (e.g., rising edge, falling edge, or both).
   • Adjust the voltage threshold to match the expected signal levels.
3. Measure the Time Interval and Calculate Frequency:
   • Start the measurement and observe the waveform displayed on the device.
   • Use the time cursors to measure the period between two consecutive rising or falling edges.
   • Calculate the signal frequency using the formula: Frequency (Hz) = 1 / Period (seconds).

Expected Outcome:

By completing this experiment, you will develop the ability to accurately measure signal timing and frequency, a crucial skill in debugging and designing electronic systems.
