EXTECH MS420 Handheld Digital Oscilloscope

EXTECH MS420 Handheld Digital Oscilloscope dual channel optimizes the position, range, timebase, and triggering to guarantee a stable display of virtually any waveform. The multimeter automatically measures twenty different functions including frequency, cycle, average, peak to peak, and RMS. Up to 4 waveforms can be stored and recalled at one time.

Multiple modes ensure the most accurate data possible: average mode for smoothing waveforms, and persistence mode for observing dynamic signals. Autoscale automatically configures trigger mode where the oscilloscope can measure a waveform without a triggering condition. XY mode and FFT function help the viewer understand the relationship between channels one and two.

Other features include 20MHz bandwidth, waveform math, and a real time clock. The included USB interface and compatible software enable the user to transfer waveforms and data to any PC.
