Multimiter Oscilloscope

Description

The multimeter oscilloscope is a versatile 3-in-1 handheld test instrument designed for electronic maintenance, field troubleshooting, electrical repair, and hardware debugging. Combining a dual-channel oscilloscope, a high-precision digital multimeter, and a DDS function signal generator into an ergonomic, rugged housing, it serves as a complete portable diagnostic setup.
