The GOS-620FG is a general purpose analog oscilloscope with a 20MHz bandwidth. Aside from the
basic functions, such as 1mV/div~5V vertical sensitivity, 0.2uS/div~0.5S/div horizontal sweep time,
and practical Auto/Norm/TV-V/TV-H trigger modes, the GOS-620FG offers extra function generating
features required for most class experiments and electrical production lines. The affordably priced
GOS-620FG is capable of generating Sine/Square/Triangle waveforms in the frequency ranges from
0.1Hz~1MHz (7 range) with sine wave distortion as low as 2%.
The GOS-310, 10MHz analog oscilloscope is designed for education, hobby and maintenance use. The
GOS-310 is applicable for various market fields with a sensitivity of 5mV/div, internal and external
triggering and a number of triggering modes (Auto, Norm, Ext and TV sync.). A 10MHz bandwidth,
single channel operation, a light 4.6kg weight and a compact design make the GOS-310 the best choice
for an affordable analog oscilloscope with effective performance.
