Description
The LBO-522 oscilloscopes are portable ones with the functions of 5mV/div.(20[35] MHz), 500 µV/div. (5MHz), maximum sweep ratio 40[20] ns/div. (MAG x 5(10)), equipped with a 6-inch rectangular [metal-back] CRT with high brightness, internal graticule, and vertical sensitivity magnifier. It has a wide range of applications in production and service areas for measurements and testing of TV sets, VTR, and computer peripheral equipment. The provided TV synchronization separator, variable hold off and V-AXIS magnifier functions are useful for those applications.
