Description:
The DWM-Air9000P is a fully functional, stable, and reliable small handheld high-precision power consumption analyzer that supports PC-side software.
Features:
Powered through a USB-C interface for measuring the voltage and current of low-power devices.
Suitable for battery-powered products, supporting specified voltage output (0~5V).
Supports current limiting output, allowing for setting any current limiting value within the range of 0~2A.
The current measurement range of 0~2A with a measurement accuracy of ±0.1% ±3 digits and a minimum resolution of 0.1μA.
Voltage measurement range of 0~5V with a measurement accuracy of ±0.1% ±3 digits and a minimum resolution of 1mV.
OCP overcurrent protection automatically limits the current output to below 1.5A in case of a circuit short-circuit.
Multiple-channel synchronous current sampling with no shift delay, a sampling rate of up to 10KHz to meet low-power testing requirements.
Connectable to PC-side software for viewing and analyzing current waveforms, catering to power consumption testing needs of cellular modules, Bluetooth chips, Wi-Fi chips, etc.
Command-line tools are available for capturing serial port data on any device (Win/Linux/Mac) and importing it for viewing using PC-side software.
