Model Bluetooth® low energy (BLE) RF-PHY receiver tests specific to blocking, intermodulation and carrier to interference (C/I) performance as per the Bluetooth RF-PHY Test Specifications [ 1 ] using Communications Toolbox™ Library for the Bluetooth Protocol.

Perform Bluetooth® low energy (BLE) radio frequency (RF) physical layer (PHY) transmitter tests specific to modulation characteristics, carrier frequency offset, and drift using Communications Toolbox™ Library for the Bluetooth Protocol. The test measurements compute frequency deviation, carrier frequency offset, and drift values. This example also verifies whether these test measurement values are within the limits specified by the Bluetooth RF-PHY Test Specifications [ 1 ].

Perform Bluetooth® basic rate (BR) radio frequency (RF) physical layer (PHY) transmitter tests specific to modulation characteristics, carrier frequency offset, and drift using the Communications Toolbox™ Library for the Bluetooth Protocol. The test measurements compute frequency deviation, carrier frequency offset, and drift values. This example also verifies whether these test measurement values are within the limits specified by the Bluetooth RF-PHY Test Specifications [1].

Perform Bluetooth® enhanced data rate (EDR) radio frequency (RF) physical layer (PHY) transmitter tests specific to modulation accuracy and carrier frequency stability using the Communications Toolbox™ Library for the Bluetooth Protocol. The test measurements compute the initial frequency offset, root mean square (RMS) differential error vector magnitude (DEVM), and peak DEVM values. This example also verifies whether these test measurement values are within the limits specified by the Bluetooth RF-PHY Test Specifications [1].

In the design of wireless communications links between two sites, issues of range, throughput, and received signal quality are of critical importance to the system engineer. Link budget analysis accounts for all gains and losses in the communication link. Some factors and design choices, such as propagation path length, signal polarization, and antenna feed cable, degrade signal quality, while others, such as the power amplifier and antenna size, can increase transmitted signal strength.

Use the comm.EVM System object™ to measure the error vector magnitude (EVM) of a simulated IEEE® 802.15.4 [ 1 ] transmitter. IEEE 802.15.4 is the basis for the ZigBee specifications.

Measure and calibrate for the frequency offset between a transmitter and a receiver at the receiver using MATLAB® and Communications Toolbox™. You can either use captured signals or receive signals in real time using the Communications Toolbox Support Package for RTL-SDR Radio. The receiver monitors the received signal, calculates the frequency offset between the transmitter and the receiver and displays it in the MATLAB® command window.

Measure and calibrate for transmitter/receiver frequency offset at the receiver using Simulink® and Communications Toolbox™. You can either use captured signals or receive signals in real time using the Communications Toolbox Support Package for RTL-SDR Radio. The receiver monitors the received signal, calculates and display the transmitter/receiver frequency offset.
