The Keysight N7109A Multi-Channel Signal Analyzer is a scalable measurement hardware platform for complex signal analysis in advanced wireless technology development. It delivers phase-synchronous MIMO RF performance across up to 8 channels, supporting LTE beamforming, carrier aggregation, and cross-channel measurements. The system integrates with Keysight 89600 VSA software to enable fast, multi-standard analysis from 20 MHz to 6 GHz per channel.
