Bluetooth® Measurement Suite

A suite of measurement functions to characterize Bluetooth® Basic Rate (BR), Enhanced Data Rate (EDR) and Low Energy (LE) radio transceivers in accordance with the requirements of Bluetooth® Specification 1.2/2.0/2.0+EDR/2.1/2.1+EDR revision 2.1E1(2008)/ 4.0.

The Bluetooth® measurement suite enables fast measurement of key signal characteristics of Bluetooth BR, EDR and LE transceivers such as burst power, modulation accuracy, initial and maximum frequency error and origin offset and Receiver sensitivity (BER).

The Bluetooth® measurement suite is suitable for characterizing devices operated in a non-signalling test mode. Measurement results for burst length, position, rise and fall times and power are provided for the entire packet as well as the individual GFSK and PSK modulated elements within the packet. For PSK modulation, the DEVM is reported together with max frequency error and origin offset. Time domain trace displays are provided for burst power, GFSK frequency deviation and DEVM. Additionally PSK modulation can be viewed as a constellation diagram.

Receiver sensitivity (BER) test for signals adhering to Test Suite Structure (TSS) and Test Purposes (TP) System Specification 1.2/2.0/2.0+EDR/2.1/2.1+EDR revision 2.1E1(2008)/4.0 can be performed either in single ended or loopback mode. In loopback mode the device is configured to re-transmit received packets and the measurement suite performs the measurement and displays the result. In this case receiver and transmitter measurements can be performed concurrently.
