NATIONAL INSTRUMENTS PXIe-5840 Bluetooth Test Toolkit User Manual

Built for Bluetooth Characterization Test and Measurement
The Bluetooth Test Toolkit gives you direct and fine control over the generation and analysis of Bluetooth waveforms with industry-leading speed and accuracy. Use the Bluetooth Test Toolkit to characterize a variety of Bluetooth connectivity products, such as RF front end components, wireless modules, and enduser devices.
The Bluetooth Test Toolkit gives you the flexibility to control your measurement system manually with the toolkit’s generation and analysis soft front panels, as well as to automate your bench with an extensive system design software API for LabVIEW, C, or .NET. You will benefit from a large collection of available example code when programming and automating your Bluetooth measurement systems.
Characterize your device with the toolkit’s comprehensive support for the latest features of the Bluetooth standard, including Low-Energy, extended payload, and long-range packets that are part of the Bluetooth 5.0 standard.

Key Features

Bluetooth Classic, Low-Energy, and Direct Test Mode
The Bluetooth standard now defines specific Bluetooth Low-Energy (BLE) RF PHY Test Cases and a new Direct Test Mode (DTM) for DUT control to make sure that Bluetooth Low-Energy devices from all manufacturers operate properly. This standardization also verifies that a basic level of system performance is guaranteed for all BLE products. With both DTM and a more relaxed RF PHY specification for Bluetooth Low-Energy, fewer PHY test cases and optimized test case implementations contribute to much shorter BLE RF PHY test times.
The NI Bluetooth Test Toolkit supports these BLE measurements and the new packet types associated with them, such as:

LE Packet

LE Extended payload packet (255 bytes)
LE-Enhanced (1 and 2 Mbps)

LE-Long range (125 and 500 kbps)

Additionally, the toolkit ships with a Direct Test Mode Interactive Example to help you control and test BLE DUTs easily.

Fast and Accurate Measurements
Combine the Bluetooth Test Toolkit with a VST to achieve industry-leading modulation and spectral measurements; the average time for a DEVM measurement is less than 33 ms.

Simulation
The Bluetooth Test Toolkit enables you to simulate and manipulate Bluetooth signals. You can also inject various impairments to characterize effects on the resulting signal measurements.

Soft Front Panel

Use soft front panels (SFPs) to generate and analyze Bluetooth signals, define custom payloads, and inject signal impairments such as noise, IQ imbalance, skew, and DC offset. Furthermore, the SFPs allow you to save waveforms and measurements for either later modulation and spectral analysis or for loading equivalent settings into the programmable API.

Application Programming Interface (API)

The Bluetooth Test Toolkit includes an API for LabVIEW, C, and .NET, with which you can create custom code for all kinds of test scenarios or custom settings. The API gives you fine control over the Bluetooth packets and it includes an extensive library of example code to get you started quickly on the many different Bluetooth measurements for the various types of packets, including Bluetooth Low Energy.

Platform-Based Approach to Test and Measurement

What Is PXI?
Powered by software, PXI is a rugged PC-based platform for measurement and automation systems. PXI combines PCI electrical-bus features with the modular, Eurocard packaging of CompactPCI and then adds specialized synchronization buses and key software features. PXI is both a high-performance and low-cost deployment platform for applications such as manufacturing test, military and aerospace, machine monitoring, automotive, and industrial test. Developed in 1997 and launched in 1998, PXI is an open industry standard governed by the PXI Systems Alliance (PXISA), a group of more than 70 companies chartered to promote the PXI standard, ensure interoperability, and maintain the PXI specification.

Integrating the Latest Commercial Technology
By leveraging the latest commercial technology for our products, we can continually deliver highperformance and high-quality products to our users at a competitive price. The latest PCI Express Gen 3 switches deliver higher data throughput, the latest Intel multicore processors facilitate faster and more efficient parallel (multisite) testing, the latest FPGAs from Xilinx help to push signal processing algorithms to the edge to accelerate measurements, and the latest data converters from TI and ADI continually increase the measurement range and performance of our instrumentation.

PXI Instrumentation

NI offers more than 600 different PXI modules ranging from DC to mmWave. Because PXI is an open industry standard, nearly 1,500 products are available from more than 70 different instrument vendors. With standard processing and control functions designated to a controller, PXI instruments need to contain only the actual instrumentation circuitry, which provides effective performance in a small footprint. Combined with a chassis and controller, PXI systems feature high-throughput data movement using PCI Express bus interfaces and sub-nanosecond synchronization with integrated timing and triggering.
