XJ4822,XJ4822B type CRT readout semiconductor transistor characteristic graphing instrumentDetailed product description：

The XJ4822 and XJ4822B CRT readout semiconductor transistor characteristic graphing instrument has a novel appearance, advanced technology, and easy operation. It can test static parameters of various diodes, transistors, field-effect transistors, etc. The reading of cursor measurement numbers brings convenience to users, and the display of two cluster curves is particularly convenient for pairing various parameters of the device. When testing high-power devices, a single pass method can be used. After being equipped with a 3KV test bench, the Vc can reach 3KV.
Cursor measurement, character reading, enabling various static parameter packaging β and Gm to be measured by cursor and read by characters.
Dual family display is used to pair various parameters
The maximum test power is nearly 100W
Ladder voltage ± 10V+△ VB ± 5V, low internal resistance, especially suitable for high-power VMOS tube testing
Maximum VC up to 3000V (optional)
Overcurrent alarm and power outage
