The bottom line: it combines a two-channel \u003cstrong\u003ehandheld oscilloscope\u003c\/strong\u003e, a 10000-count multimeter and a DDS signal generator in a single portable unit, making it the best buy for users who value space, battery operation and waveform export more than top-end laboratory bandwidth.
