How to Use the Keysight EDUX1002A: A Step-by-Step Guide

Alright, let's get down to the fun part: actually using the Keysight EDUX1002A. Don't worry, it's not as intimidating as it looks! Here's a step-by-step guide to get you started.

Step 1: Setting Up Your Oscilloscope

Power On: First things first, plug in the scope and turn it on. You should see the screen light up and the scope go through its startup sequence. Let it initialize.
Connect Probes: The EDUX1002A comes with probes. These are the connectors that carry the signal from your circuit to the scope. Attach the probe to the appropriate channel input on the front panel of the scope. Make sure the probe is properly connected and that you select the correct attenuation factor (usually 1x or 10x) on the probe itself, depending on your application.
Probe Compensation: Many probes require compensation to ensure accurate measurements. This is a simple process: Connect the probe to the probe compensation output on the front panel of the scope. Adjust the probe's compensation trimmer (usually a small screw) until the waveform on the screen is a square wave with flat tops and bottoms. This ensures that the probe isn't distorting your signal.

Step 2: Basic Measurements

Connect to Your Circuit: Now, connect your probes to the circuit you want to measure. Make sure the ground clip of the probe is connected to a ground point in your circuit, and the probe tip is connected to the point you want to measure.
Adjust Vertical Scale: Use the vertical scale controls (Volts/Div) to adjust the voltage range so that your signal fits comfortably on the screen. Too high, and you won't see anything. Too low, and you'll clip the signal (lose the top or bottom).
Adjust Horizontal Scale: Use the horizontal scale controls (Time/Div) to adjust the time scale. This determines how much time is represented on the screen. Adjust it to see a clear representation of your signal over time.
Triggering: The trigger controls are crucial. They tell the scope when to start displaying a waveform. Set the trigger level and trigger mode (edge, pulse, etc.) to get a stable display of the signal. Edge triggering is the most common.

Step 3: Analyzing Waveforms

Observe the Waveform: Look at the waveform on the screen. Is it a sine wave, a square wave, or something else? Is it distorted in any way?
Use Cursors: The EDUX1002A has cursors that you can use to measure specific points on the waveform, such as voltage levels and time intervals.
Use Automatic Measurements: The scope also has automatic measurement functions. Use these to quickly determine parameters like frequency, amplitude, and period.
Experiment and Learn: The best way to get comfortable with the scope is to experiment. Try measuring different signals and adjusting the controls to see how they affect the display.
