Bluetooth measurement application

Expand the capabilities of your M9391A and M9393A PXIe vector signal analyzers (PXI VSAs) with Keysight's library of measurement applications - the same applications used to increase the capability and functionality of its X-Series signal analyzers. Eleven of the most popular applications are now available for use with Keysight's new M9393A PXIe performance VSA and the M9391A PXI VSA. When you combine the raw hardware speeds of the PXI VSAs and the X-Series measurement applications for modular instruments, you can test more products in less time, while ensuring measurement continuity from design to manufacturing.

The M9081A Bluetooth measurement application transforms the PXI VSAs into standard-based Bluetooth RF transmitter testers by adding fast, one-button RF conformance measurements to help you design, evaluate, and manufacture your Bluetooth devices. The measurement application is standard-compliant to the Bluetooth Core Specification to verify your Bluetooth design with confidence and support manufacturing with a single application covering basic rate, EDR and low energy technologies for production.

Proven algorithms and a common user interface across the X-Series analyzers and modular PXI VSAs create a consistent measurement framework for signal analysis that ensures repeatable results and measurement integrity so you can leverage your test system software through all phases of product development. The Bluetooth measurement application is just one in a common library of several measurement applications. You can further extend your test assets by utilizing up to four PXI VSAs with one software license.

Keysight's X-Series applications for modular instruments also include a unique "Resource Manager" that provides direct access to PXI VSA hardware drivers for the fastest power and spectrum-based measurements, while simultaneously using the X-Series applications for fast modulation quality measurements and the 89600 VSA software for fast spectrum measurements.

Bluetooth technology overview

Bluetooth is an open wireless technology standard for exchanging voice and data over short distances between fixed and mobile devices, creating personal area networks (PANs) with high levels of security. Bluetooth wireless technology eliminates the need for interconnection cables between information appliances.

The Bluetooth Special Interest Group (SIG), chartered to advance and promote Bluetooth wireless technology, has defined a test specification for conformance testing on the RF layer.

Bluetooth uses a radio technology called frequency-hopping spread spectrum (FHSS), and the design emphasis is on very low power, extremely low cost, and robust operation in the globally unlicensed, interference-dominated RF environment of the Industry, Scientific and Medical (ISM) band at 2.4 GHz.

In Classic Bluetooth, which is also referred to as basic rate (BR) mode, the modulation is Gaussian frequency-shift keying (GFSK). It can achieve a gross data rate of 1 Mbit/s.

Enhanced data rate (EDR) is an enhancement to the Bluetooth Core Specification version 1.2 (v1.2) and is described in the Bluetooth version 2.0 specification. It uses π/4-DQPSK and 8DPSK modulation giving 2 and 3 Mbit/s data transfer rates, respectively.

Bluetooth low energy (LE) technology was finalized in December 2009 by the Bluetooth SIG. This ultra low power Bluetooth technology is intended to discover new use case scenarios for tiny low power devices that were not served by existing local connectivity solutions. Two modes have been designed: single-mode and dual mode. The Bluetooth low energy dual-mode chips support both Bluetooth low energy and Classic Bluetooth technology; single-mode chips support only Bluetooth low energy. The low energy wireless technology is part of the Core Specification v4.0.

Additionally, the Bluetooth new Core Specification version 2.1 + EDR, has been published by the SIG with security improvements, simplified pairing and power consumption. These will offer more advances in short range wireless technology and make it easier for consumers to connect.
