The five-strong WQ4829 digital storage transistor curve tracers Digital Storage: The machine can store 10 graphics, can also be stored to a computer through the USB interface infinite amount. Can be saved as a specific file format, and can also be saved as JPG, BMP and other image formats. The data can be stored in a computer printer to print pictures can also be downloaded through the USB interface to the instrument. 
 The synchronized display: high-speed USB communication devices can test the graphics synchronization displayed on a computer screen, so that the size of the display interface to get the unlimited expansion. 

 Parameters: automatically measure and display the voltage, current, beta, gm measurement value and set parameters. 

 The paired selection: a static graphics and a dynamic graphics can be displayed simultaneously, convenient intuitive paired the two devices. 

 Rapid screening: a parameter under certain conditions can set upper and lower limits, the measured parameter exceeds the range will sound and light alarm. 
 X-axis systems: 

 1. Collector the voltage Vce: 10mV/div ~ 50V/div maximum 500V 

 Base voltage Vbe: 50mV/div ~ 1V/div 

 3. Diode reverse voltage Vd: 100V/div 500V/div maximum 5000V 

 Step current: 

 WQ4829: 0.2μA / grade level ~ 0.2A / Max 2A 

 The ladder voltage: 10 mV / ~ 1V / level, maximum 10V.
