Agilent Technologies has introduced enhancements to its N7109A multichannel signal analyser for emerging multichannel LTE, LTE-Advanced and MIMO RF measurement requirements, including LTE antenna beam-forming and LTE-Advanced carrier aggregation. Building on the N7109A’s strengths for WiMAX and LTE MIMO measurements, these new enhancements enable designers to stay one step ahead of rapidly evolving LTE and LTE-advanced communication standards.
Using the latest 89600 VSA software release 15, the N7109A delivers phase synchronous measurements with up to eight RF channels in a single mainframe. It delivers verification and visualisation of TD-LTE base station RF antenna beam-forming, including transmission mode 7 (8x1 single layer using port 5) and transmission mode 8 (8x2 dual layer using ports 7 and 8). The analyser can perform cross-channel measurements, including frequency response, cross correlation, coherence and more.
The system provides independent centre frequency tuning for each tuner module. It can be used to perform LTE-Advanced carrier aggregation measurements with each channel tuned to a different component carrier, or multiple channels tuned to each component carrier for MIMO signals.
Simultaneous uplink and downlink measurements are possible.
Integrated with Agilent’s 89600 VSA software, a step-by-step correction wizard provides accurate amplitude and phase measurements at the device under test.
