Overview

Hangzhou Aihua AWA6290 Multi channel Signal Analyzer

Product Details

The AWA6290 series multi-channel signal analyzer is a signal analysis instrument developed using computer multimedia technology. Strict synchronization between multiple channels, high-precision sampling, can be used for the acquisition, spectrum analysis, and related applications of analog signals such as noise and vibration. The analyzer consists of two parts: a signal generator and a signal collector. The generator has two independent channels, while the collector has an independent channel. Using Ethernet for data communication, convenient to use.
