RF Transmitter Tests
With the X-Series signal analyzers and the Bluetooth measurement application, you can
perform the RF layer test procedure and specification (TSS/TP 4).
Standard-based RF transmitter tests
The Bluetooth specifications are developed and licensed by the Bluetooth Special
Interest Group (SIG). The Bluetooth Test Specification document contains the Test Suite
Structure (TSS) and Test Purpose (TP) to test the Bluetooth RF layer including Enhanced
Data Rate. This specification is a basis for conformance tests of Bluetooth devices, giving
a high probability of air interface inter-operability between different manufacturer’s
Bluetooth devices. For the Bluetooth low energy, it is integrated into an existing Classic
Bluetooth controller, so its architecture shares much of Classic Bluetooth’s existing radio
and functionality resulting in a minimal cost increase compared to Classic Bluetooth.
The Keysight X-Series Bluetooth measurement application refers to the following
Bluetooth RF test specifications:
–– Bluetooth Test Specification 1.2/2.0/2.0+EDR/2.1/2.1+DER
–– Bluetooth Low Energy RF Test Specifications: RF-PHY.TS/4.0/4.2
Table 2 provides a list of tests with their test purpose identifiers and corresponding
measurement applications for transmitter tests only.
