Extech Digital Oscilloscope – MS420
Extech’s MS420 is a Dual channel 20MHz Oscilloscope with 3.8″ color LCD display. It offers a range of capabilities for effective troubleshooting of electronically controlled systems. With 20 MHz bandwidth and conveniences like auto-set which optimizes the position, range, timebase, 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 recurring tests, you can store and recall up to 4 waveform screens and setups to save time from job to job. This CAT II-rated oscilloscope includes complete DMM functions that are displayed on the large 3. 8″ (97mm) color LCD display.
