Description

Extech MS420 20MHz 2-Channel Digital Oscilloscope

Extech's MS420 20 MHz 2-Channel Digital Oscilloscope offers a range of capabilities for effective troubleshooting of electronics and electronically controlled electrical systems. With 20 MHz bandwidth and conveniences like auto-set which optimizes the position, range, time base, and triggering to assure a stable display of virtually any waveform, the MS420 can be used in field repairs or bench duty.

To identify subtle problems, Peak Detect features a fast 50 ns glitch capture. Core functions like XY Mode, FFT function, Trigger Hold off, Waveform Math, Averaging Mode and Persistence Mode all ensure you can confidently troubleshoot problems using a variety of approaches. To start up recurring testing routines, you can store and recall up to 4 waveform screens and setups to save time from job to job. This CAT II-rated oscilloscope extends its functionality with complete DMM functions that are displayed on the large 3. 8" (97mm) color LCD display.

The Extech MS420 20MHz Oscilloscope can complete waveform math using addition, subtraction, multiplication and division and there is also an average mode which can be set for smoothing waveforms, as well as a persistence mode which enables users to observe dynamic signals.  True RMS multimeter functions are present in the Digital Oscilloscope and include AC/DC voltage and current, diode, continuity, capacitance and resistance.
