Look for the "Port" or "COM" dropdown menu. If your drivers are correct, you should see a specific COM port listed. Select it.
Extract the downloaded archive to a dedicated folder on your computer desktop. Open the folder and locate the driver installer file (often labeled CH340 Driver or similar, depending on the internal USB-to-serial chip used). Run the installer as an administrator and follow the on-screen prompts to ensure your PC can communicate with the oscilloscope. Step 3: Boot the DSO-TC2 into Bootloader Mode
Firmware resides in external flash, with a bootloader in MCU’s internal ROM. fnirsi dsotc2 firmware
Improving the automatic detection of components like NPN/PNP transistors, MOSFETs, diodes, and resistors.
The device will automatically apply the new firmware and reboot.
The FNIRSI DSO-TC2 is a remarkably versatile and compact piece of test equipment. It has become an essential tool for many electronics enthusiasts by ingeniously integrating multiple functions—a digital oscilloscope, an electronic component tester (LCR meter), and a PWM signal generator—into one portable, pocket-sized device. This detailed guide will walk you through every aspect of the DSO-TC2's firmware, from understanding its core function and types to performing a safe and successful upgrade.
