The MOS-620 is a 20MHz dual-channel analog oscilloscope with stable performance and easy operation, becoming a practical tool in the electronic testing field with rich functions and reliable design. It adopts a 6-inch high-brightness internal-scale rectangular CRT, with an accelerator voltage of 2kV, capable of presenting clear trajectories even under high-speed scanning. The vertical system sensitivity covers 5mV~5V/DIV (10 adjustable gears), with a bandwidth of DC~20MHz and a rise time of approximately 17.5nS. Combined with the 10x scan expansion function, the scan speed can be increased to 20ns/div, easily capturing details of high-frequency signals.
This oscilloscope has outstanding practical features: it supports dual-channel simultaneous display (alternate/intermittent mode switching), X-Y operation, and TV synchronization function, enabling observation of TV field/line signals or two unrelated signals. The ALT trigger function ensures stable display of signals with different frequencies. The input impedance reaches 1MΩ/25pF, with a maximum input voltage of 300V (DC+AC peak). It is equipped with a 2Vp-p/1kHz calibration signal for easy probe calibration. Adopting Japanese electronic encoding switches and sealed attenuation switches, it is lightweight and durable, meeting high-precision signal measurement needs in laboratories, production lines, and other scenarios, with simple operation and stable reliability.
