  • Description

    Extech MS420 20MHz 2 Channel Digital Oscilloscope

    Designed to quickly and easily identify, analyze and calculate the frequency of waveforms.

    Features a colour LCD display, 97mm across and comes with an auto set function. The auto set function optimises the range, time-base, position and triggering. There is also a trigger hold-off function included, which all help to ensure that viewing multiple waveforms is not only easy but stable too.

    There is a peak function for 50ns glitch capture and an XY mode and FFT function in order to view all component frequencies and there are twenty excellent automatic measurements included with this 2 Channel Digital Oscilloscope; which include, average, cycle, frequency, peak to peak, RMS and then fifteen more valuable measurements. 

    This 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 als a feature and include AC/DC voltage and current, diode, continuity, capacitance and resistance.

    Extech's oscilloscope is able to store and recall up to four waveforms and setups and includes USB interface and Windows compatible software, which can be used for transferring waveforms and data from the instrument as and when needed.

    The Extech MS420 Oscilloscope comes with a 20MHz bandwidth, 2 Channel Digital Oscilloscope along with a capacitor measuring module, 1 x / 10 x scope probes, AC adapter and charger, adjustment screwdriver, test leads and a solid case in which to carry the 180 x 113 x 40 mm oscilloscope in. Also comes with a 2 Year Warranty.
