LitePoint’s Bluetooth Low Energy over-the-air measurement solution
The new LitePoint IQxel-M™ Bluetooth Advanced measurement system is a major advancement in the speed and efficiency for performing over-the-air testing of Bluetooth Low Energy peripheral and beacon devices. Using LitePoint’s proprietary measurement techniques, testing Bluetooth devices has been made simple and the system performs comprehensive transmitter and receiver measurements in a matter of seconds. The solution is optimized for both engineering and manufacturing and works with all BLE peripheral and beacon devices, regardless of chipset.
Advanced Measurement Methodology
BT Smart devices use dedicated advertising channels to transmit beacon signals or to establish a connection with a controller. These advertising channels are distributed across the 2.4 GHz band, providing an excellent method to characterize a device at multiple frequencies. The IQxel-M with BT Advanced measurement solution uses these advertising channels to perform transmitter and receiver measurements, providing excellent coverage and confidence in the parametric performance of the device. The device is tested using its normal commercial firmware, not test firmware, and therefore improves confidence that the results are correlated with actual performance of real devices.
Applications from Engineering to Manufacturing
In an engineering environment, transmitter power, transmitter quality, and receiver sensitivity are important measurements to perform and IQxel-M performs these quickly, with high accuracy and repeatability. Measurement results are reported on all advertising channels, giving confidence in the RF performance across the 2.4 GHz band. In manufacturing, speed is equally as important as the test coverage, and for most devices, a typical transmitter and receiver test can be performed in <5 seconds for all 3 advertising channels. This is a very rapid test that ensures both the transmitter and receiver are functional and performing within user defined specifications.
