The AOS03 is a compact handheld oscilloscope multimeter built for field diagnostics, electronics repair and troubleshooting where you need both waveform viewing and standard meter functions in one device. It combines a 2-channel digital oscilloscope, a 25,000-count True RMS multimeter, and a signal generator in a rugged handheld body made with dual-injection molding for improved grip and durability. The large 3.5-inch IPS full-view color display keeps waveforms and readings easy to interpret from different angles, which is especially useful in tight workspaces.
For oscilloscope work, the AOS03 supports a 50MHz bandwidth with a maximum sampling rate listed up to 280MS/s (real-time sampling is also specified as 200MSa/s), a maximum waveform capture rate of 250,000 wfm/s, and a 128KB record length for capturing and reviewing signals. As a multimeter, it offers fast sampling (3 readings per second), True RMS measurement, data hold, backlight, low battery indication and automatic power-off.
