XJ4393 type 300MHzCRT readout two track oscilloscopeDetailed product description：

The XJ4393 dual track oscilloscope has a frequency bandwidth of 300MHz, which is suitable for observing ultra high speed pulses and nanosecond signals. This instrument has functions such as envelope synchronization, ultra-high frequency synchronization, automatic triggering, TV synchronization, single scan, etc. It uses a 5 "high brightness CRT. This instrument has advanced CRT digital display readout function. Through cursor measurement, the △ V, △ T, 1/△ T values of the measured signal and the test level are displayed in character form on the screen,

The XJ4393 300MHz CRT readout two track oscilloscope is an ideal high-frequency band oscilloscope with powerful functions, easy operation, and suitable for many fields such as high-speed electronic computers, lasers, communications, and nuclear physics. Vertical system
