This has a dimension of 7x4.4x1.6" and a weight of 24.3oz or 690grams. This extech oscilloscope has a real time sample rate of 100 MS/s and a rise time of 17.5ns. As what the title said, Extech Ms420 has two channels and a record length of 6K points per channel. The glitch capture is 50ns. The vertical sensitivity of the extech oscilloscope is 5mV to 5V/div and its vertical solution is 8 bits. The time base range is 5ns to 5s/div. The sample mode of the Extech oscilloscope includes Sample, Peak Detect and Average. The trigger modes include free run, edge, single shot and video. The trigger source of Ms420 are channel one and channel two. The trigger couplings are AC and DC. The input impedance is 1MΩ/20pF and the max input voltage is 400V on its peak. The cursor measurements used in Ms420 are the time and voltage.

When it comes to the true RMS multimeter functions, the AC/DC voltages include 400mV, 40V, 4V and 400V. The AC/DC current would be 300mA, 40mA and 20A. The resistances of the Ms420 Extech oscilloscope are 400Ω, 40kΩ, 4kΩ, 400kΩ and 40MΩ. The capacitance ranges from 51.2nF to 100µF. The PC interface of this Extech oscilloscope is USB cable.

There are certain features of this Extech Ms420 oscilloscope. These features include an auto-set function which makes use and optimizes the range, position, triggering and time base to guarantee a stable demonstration of virtually any other waveform. The model Ms420 digital oscilloscope also features 5 automatic measurements including cycle, frequency, average, RMS and peak to peak. Ms420 also makes use of a Peak Detect capacity that has a XY mode and for a 50ns glitch capture. It has an Average Mode that is used for smoothing waveform and also a Persistence Mode used for observing active signals. Furthermore, the Extech oscilloscope can recall and store from up to 4 waveforms setups and screens. It has Math features that allow users to subtract, add, divide and multiply.

The component makes use of a software and USB interface used for transferring data and waveforms. With an utmost input electrical energy of 400 Volts and a bandwidths of 20MHz, the extech Ms420 oscilloscope comes complete with a test lead, double 1x/10x oscilloscope probes, Windows 88/95/NT/ME/XP/2000 compatible Universal Serial Bus cable and software, capacitor calculating module and a current shunt. In this oscilloscope, adjustment screw driver, hard carrying case and a universal AC charger or adaptor are also included. The power supply is six hours Li-ion rechargeable battery.

Additionally, the ms420 oscilloscope also comes with a dual testing or a troubleshooting of several printed circuit boards and also electronic assemblies. The software PC screens can display graphical waveform and analog bar graph. There is a trigger hold off function of Ms420 that stabilizes complex waveforms.

Here are some additional information about Extech Ms420 oscilloscope:

The auto-set feature allows the digital oscilloscope to display and measure unknown signals automatically. This feature is useful in quickly checking multiple signals.

Persistence Mode allows a user to resist a waveform on the display, at the same time, overlapping the current waveform.

The Peak Detect is used to display glitches and other asynchronous waveforms.

You can use AC-coupling in observing a small ac signal that goes with the dc signal.

Each channel of the Extech oscilloscope has its own exclusive menu and each of the items can be set correspondingly based on the specified channel.

The trigger system determines when the display and acquisition of waveform data occurs.
