Introduction

Adapt as MIMO Testing Evolves

Overview

In the development of next-generation wireless technologies, MIMO measurements are becoming an essential part of every R&D engineer’s toolkit. From 802.11n to LTE-Advanced and beyond, the Keysight Technologies, Inc. N7109A multi-channel signal analyzer provides excellent MIMO RF performance at attractive price points for two-, four- and eight-channel systems.

Product Description

The N7109A combines scalable measurement hardware with the MIMO and multi-channel measurement capabilities of the industry-leading Keysight 89600 VSA software.

This combination enables fast, informative measurements on devices ranging from 2x2 to 4x4 to 8x8, including LTE beamforming and a variety of cross-channel characterization measurements.

Applications

  •  Wireless communications
  •  Wideband signal analysis
  • Features
  •  Frequency range per channel: 20 MHz to 6 GHz
  •  40 MHz bandwidth per channel (preselected and independently tunable).
  •  Up to 8 phase synchronous measurement channels for LTE antenna beamforming, 8x8 MIMO, and a variety of cross-channel measurements—frequency response, cross correlation, coherence, etc.
  •  Independently tunable measurement channels for LTE-A Carrier Aggregation (both in-band and multiband), simultaneous uplink/down link measurements, and more.
  •  Correction Wizard provides superb amplitude and phase accuracy at the device-under-test.
  •  Fully integrates with 89600 VSA software for fastest measurement results.

Customer values

Adapt as MIMO Testing Evolves

Make multi-channel and MIMO measurements from 2x2 to 4x4 to 8x8

The basic measurement configuration is shown in the diagram below. Up to eight vector signal generators provide inputs to the MIMO device-under-test (DUT) and an N7109A with two, four or eight channels measures the outputs. The 89600 VSA software runs on the host PC, providing simultaneous signal acquisition and analysis.

Apply advanced signal generation

Our range of vector signal generators provides outstanding signal quality at baseband, RF and microwave frequencies, plus arbitrary waveform playback and sophisticated real-time signal generation.

Examples include the N5182B MXG, E4438C ESG and E8267D PSG vector signal generators as well as the N5106A PXB baseband generator and channel emulator.

Keysight’s Signal Studio and SystemVue applications are useful additions for the creation of Keysight-validated and performance-optimized reference signals.

These PC-based software applications enable generation of numerous application-specific test signals at baseband, RF and microwave frequencies. Flexible and easy to use, they cut the time you’ll spend on signal simulation.

Get fast, flexible measurements

The N7109A is a modular, compact measurement platform. You can configure a system with one, two or four N7130A two-channel receiver modules that provide 40 MHz analysis bandwidth from 20 MHz to 6 GHz. Each channel can be independently tuned and includes a built-in preamp and multiple fixed pre-selectors, to optimize off-the-air measurements.

Processing power comes from integrated CPU and FPGA modules. These combine to deliver onboard data reduction, fast measurements and, with the Gigabit Ethernet PC link, rapid data transfers.

Even a fully loaded eight channel configuration fits into a 19-inch mainframe that’s rack mountable and just 4U high. We also include a front cover that simplifies signal connections, provides additional RF shielding, and ensures proper measurement calibration.

See Through the Complexity

The 89600 VSA software is a window into what is happening inside complex wireless devices. It is equipped to measure more than 70 signal standards and modulation types, including LTE (FDD/TDD), W-CDMA HSPA+, GSM/ EDGE Evolution, 802.16 OFDMA and ultra-wideband (UWB) MB-OFDM.

The 89600’s 20:20 trace/marker capability lets you open new windows into what’s happening. Pinpoint problems with arbitrary arrangement and flexible sizing of up to 20 measurement traces at once.

Isolate the sources of unexpected signal interactions with up to 20 markers per trace, and activate trace-to-trace coupling of markers. To help you capture and analyze random or transient events, the 89600 also provides multi-domain digital-persistence and cumulative-history displays.

The 89600 VSA software version 16 and later enables multiple independent measurements to be performed simultaneously on each N7109A measurement channel. Since each channel can be independently tuned to different frequencies, you can save test time and cost by using one N7109A to perform a variety of measurements simultaneously.
