Troubleshooting Time: Common Issues and Solutions for FNIRSI Oscilloscopes

Okay, let's be real, even the best gear sometimes acts up. Don't worry, here's a guide to troubleshooting some common issues you might encounter with your FNIRSI oscilloscope.

Issue 1: No Signal Displayed: If you're not seeing anything on the screen, first check the probe connections. Make sure the probes are securely connected to both the oscilloscope and the circuit. Verify that the probe is properly grounded. Then, double-check your input signal. Is there even a signal? Ensure that your device is turned on and functioning correctly. If you're sure there's an input signal and the connections are good, try adjusting the vertical and horizontal scales. The signal might be too small or too large to be displayed. Utilize the auto-set function, which automatically adjusts the settings to display the signal. Also, check the trigger settings. Make sure the trigger mode is appropriate for your signal. The trigger level might be set incorrectly, preventing the signal from displaying properly. Finally, if all else fails, consult the user manual. Your manual might have specific troubleshooting steps or information about the issue.

Issue 2: Distorted Waveform: A distorted waveform can be frustrating. Check the probe compensation. You might need to calibrate the probe to match the oscilloscope's input impedance. This is usually done using a calibration signal. Adjust the vertical and horizontal scales to ensure you're viewing the signal correctly. A scale that's too small or too large can cause distortion. Check the input signal itself. Does the signal have distortion? The oscilloscope is just displaying what it's receiving. And if your signal is coming from a noisy environment, that can cause distortion too. This can be resolved with proper shielding or filtering. Finally, make sure the input signal is within the oscilloscope's specifications. Signals that exceed the maximum input voltage can lead to distortion. And it's also a possibility that the oscilloscope itself has a hardware issue, in which case you will want to contact FNIRSI for support.
