: If your PC doesn't see the scope, try a different USB-C cable (some are "charge only") or ensure you have manually switched the device to MSC mode in the menu.
: Updates often improve the handshake between the device and PC software, ensuring the "Mass Storage Class" (MSC) mode works reliably for file transfers. Step-by-Step Firmware Update Guide
Turn the scope back on and verify the new version number in the menu. Troubleshooting Common Update Failures
: Early firmware had a display discrepancy where the waveform did not align correctly with the graticules at its fastest sweep speed. Version 1.5.1 fixes this, ensuring a 50 MHz signal correctly occupies 10 divisions.
: Some hardware versions lacked standard RMS measurements in the "Measure" menu. Newer firmware (typically 4.7.1+) restores or renames these commands to provide accurate readings.
: If your display appears flipped after an update, you likely flashed firmware meant for a different hardware revision. You must find the specific firmware version compatible with your hardware serial number to revert the change.
The is a popular 3-in-1 handheld oscilloscope, but early versions often shipped with bugs that hampered its 100MHz potential. Specifically, users frequently encounter a graticule display issue at the 2ns/div setting and missing RMS measurements in the multimeter or oscilloscope menus. Fortunately, a firmware update can resolve these bugs and improve stability. Key Issues Fixed by Firmware Updates
