jaejoo14 Posted November 7, 2023 Share Posted November 7, 2023 (edited) Scope Channel #1 is not working in Analog Discovery3. The same configuration as Channel #2, it has a very weak signal. Calibrated the AWG #1 and running the calibration of scope brings the exception because of weak signal. Any way to resolve it?

0 attila Posted November 7, 2023 Share Posted November 7, 2023 Hi @jaejoo14 1. Make sure the attenuation is set to 1 X 2. The input range relay may be stuck or remain in bad position due to certain software settings. Try toggling Channel 1 Range between 500 mV/div and 1V/div Does it solve the problem ? Can you hear it clicking like it is for Channel 2 ? 3. If you have calibrated the device (WaveForms/Settings/Device Manager/Calibrate), make sure the Scope 1 Gains are low values, or select Reset/Load Factory.

0 jaejoo14 Posted November 8, 2023 Author Share Posted November 8, 2023 Yes, I can hear the clicking sounds for Channel #1 and #2. Still issue. Do you think I need to contact the support for a warranty? Link to comment Share on other sites More sharing options...
0 attila Posted November 8, 2023 Share Posted November 8, 2023 Hi @jaejoo14 Contact the support for replacement. The relay on oscilloscope channel 1 is stuck on high range, so the reading is probably correct only with 1V/div and higher. Toggling the relay a few times, like changing between 500mV/div and 1V/div, should have removed temporary stuck, contact issue, oxidation. You could try the following to make sure all application settings are reset, but don't expect to help. /Applications/WaveForms.app/Contents/MacOS/WaveForms -safe-mode (For nicer app interface you could use Settings/ Options/ Style : Fusion) Link to comment Share on other sites More sharing options...
Question
jaejoo14
Scope Channel #1 is not working in Analog Discovery3. The same configuration as Channel #2, it has a very weak signal. Calibrated the AWG #1 and running the calibration of scope brings the exception because of weak signal.
Any way to resolve it?
