Extech's MS420 20 MHz 2-Channel Digital Oscilloscope has a variety of features for effective troubleshooting of electronics and electronically controlled electrical systems. The MS420, with its 20 MHz bandwidth and features like as auto-set, which optimizes the position, range, time base, and triggering to ensure a reliable display of nearly any waveform, can be utilized in field repairs or bench duties. Peak Detect has a rapid 50 ns glitch capture time to discover tiny faults. Core functions such as XY Mode, FFT function, Trigger Hold off, Waveform Math, Averaging Mode, and Persistence Mode enable you to confidently troubleshoot problems utilizing a number of ways. To begin repeating testing procedures, you can store and recall up to four waveform screens and settings to save time from job to job.
