The TOOLTOP ET120M is a pocket-size digital oscilloscope with 120MHz analog bandwidth and a 500MSa/s real-time sampling rate, on a bright 2.4-inch 320×240 colour screen. It is a handy first scope for students and a portable one for technicians repairing inverters, SMPS and control boards.
It measures 12 waveform parameters automatically, outputs a test square wave at 1kHz, 10kHz, 100kHz or 1MHz, stores up to 2500 waveforms, and runs about 6 hours on its built-in 18650 lithium cell inside a silicone protective cover.
