GOS GOS-6021/6020 Oscilloscope Operating Manual
The document begins with an introduction to the GOS‑6021/6020 oscilloscope, describing its dual‑channel 20 MHz bandwidth, CRT display, and built‑in frequency counter. It lists technical specifications such as input voltage limits, impedance, power consumption, dimensions, and environmental limits.
Subsequent sections cover safety warnings, panel layout, detailed operation methods (signal connection, vertical/horizontal controls, cursor measurements), and a maintenance chapter that includes fuse replacement, power‑supply adjustment, and cleaning instructions for qualified service personnel. This manual is written in Chinese.
