20 MHz Basic Scope

The GOS-620 oscilloscope is a portable-type, dual-channel oscilloscope with a bandwidth of DC is up to 20MHz, and its maximum sensitivity is 1mV/DIV. The time base provides a maximum sweep time of 0.2uS/DIV. The sweep speed becomes 100nS/DIV after magnifying 10 times. The oscilloscope uses a 6-inch rectangular type cathode-ray tube with red internal graticule.  The product is sturdy, easy to operate and exhibits high operational reliability.
