Multifunctional Oscilloscope

Description

The multifunctional oscilloscope is a versatile 3-in-1 handheld instrument designed for electronic repairs, field engineering, automotive diagnostics, and hardware testing. Combining a digital oscilloscope, a high-count digital multimeter, and a DDS function signal generator into an ergonomic handheld package, it provides a complete portable diagnostic setup.
