Industry trends

The digital source measure meter integrates the functions of voltage source, current source, voltmeter, ammeter, and electronic load, and is widely used in the measurement of various precision devices: semiconductor IC or components, power devices, sensors, organic materials and nanomaterials, etc. Test and analyze.

What is the principle of digital source measure meter? How does it support four-quadrant work?

1. The quadrant diagram of the power supply refers to the quadrant diagram formed with the output voltage of the power supply as the X axis and the output current as the Y axis.

2. The first and third quadrants mean that the voltage and current are in the same phase, and the device supplies power to other devices, which is called the source mode; as a positive or negative constant voltage or constant current power supply is this mode;

3. The second and fourth quadrants are reversed voltage and current. Other equipment discharges the equipment, passively absorbs the incoming current, and can provide a return path for the current, which is called hydrazine mode; solar panels and lithium batteries are in this mode when discharging experiments .
