F9642A 2D Multi-Probe Anechoic Chamber (MPAC) Pro

Data Sheets

Introduction

 

The Keysight F9642A 2D Multi-Probe Anechoic Chamber (MPAC) Pro is a shielded anechoic chamber for Protocol and Functional testing of FR2 direct far-field capability and FR1 4X4 MIMO throughput capability supporting extreme temperature control and thermal imaging.

 

Overview

 

The Keysight F9642A 2D Multi-Probe Anechoic Chamber (MPAC) Pro is a shielded anechoic chamber for Protocol and Functional testing of FR2 direct far-field capability and FR1 4X4 MIMO throughput capability supporting extreme temperature control and thermal imaging.

 

The chamber includes connections for up to six FR2 RF heads connected to a range of up to three feed antenna locations, arranged in an arc to simulate variable angles of arrivals or multiple beams. The FR2 antennas are located within the angle of +/-15° from the positioner rotation center, creating the angle of 30° for a range length of 106 cm.

 

There are four dual polarization FR1 antennas located in each corner of the roof with room for polarization rotation to provide maximal signal de-correlation.

 

Thermal camera is also located on the roof to give unobstructed view to Device-Under-Test (DUT).

 

The DUT is placed in a software-controlled positioner, capable of providing full spherical coverage.

 

 

Key Features

 

The key features of Keysight F9642A 2D MPAC Pro are:

 

• FR2 protocol, RF and functional testing with three Angle-of-Arrivals (AoA) within a 30° angular separation

• FR1 functional testing with up to 4x4 MIMO throughput

• Thermal camera

• Software to provide positioner control, Vector Network Analysis (VNA) based chamber calibration, and coordinate system mapping

• Laser-guided crosshair for accurate DUT placement

• Fully shielded and filtered

• Low path loss

• Temperature maintenance through forced air ventilation

• Lit interior facilitates working inside the chamber

 

Supported Use Cases

 

Keysight F9642A 2D MPAC Pro supports, for example, the following use cases:

 

• Software protocol testing with various antenna configurations

• RF module testing (white box testing)

• Beamforming of up to three AoAs

• Antenna testing (white box testing)

• Wireless cable connection (black box testing)

• Protocol / Demod / 1 AoA RRM (black box testing)

• FR1 4X4 MIMO data throughput

• DUT surface temperature measurement (Hot Spot)

 

Contact Keysight to discuss about further use cases as the OTA Test Bed performance is a task to evaluate with care.
