One of the limitations of handheld oscilloscopes with built-in screens is the tiny display. By utilizing a PC or tablet screen, the DDS120 software provides a large, clear view of the signal. This is invaluable when analyzing complex waveforms or comparing multiple signals simultaneously on two channels.
| Problem | Likely Fix | |--------|-------------| | “Device not found” | Wrong COM port or missing CP210x driver | | Frequency jumps erratically | Try a lower baud rate (9600) | | Software crashes on Windows 11 | Run in Windows 7 compatibility mode | | No signal output | Check if the board is in “sweep” or “power-down” mode | dds120 software
Real-time visualization of sine, square, and PWM signals. One of the limitations of handheld oscilloscopes with
Automatic calculations for peak-to-peak voltage ( Vppcap V sub p p end-sub ), frequency, RMS, and duty cycle. | Problem | Likely Fix | |--------|-------------| |
The DDS120 is a dual-channel, handheld virtual oscilloscope. Unlike traditional oscilloscopes that have a built-in screen and physical knobs, the DDS120 is a compact enclosure that connects to a computer (PC) or Android device via USB. It relies on the host device’s processing power and screen to display waveforms and manage controls.
