First EDR solution with loopback test mode
Rohde & Schwarz is now providing an option for Bluetooth® V2.0 + EDR that complements the R&S CBT and the R&S CBT32. Fitted with this option, the RF testers can perform transmitter and receiver measurements on EDR Bluetooth® instruments and modules without requiring any external equipment. The solution will also support the loopback test mode. Rohde & Schwarz is the first company to successfully implement the loopback function in its RF testers.
The new Bluetooth® standard V2.0 + EDR (enhanced data rate) enables data transmission rates that are up to three times higher than the previous V1.1 und V1.2 standards. As a result, labs and production now require flexible and versatile T&M equipment to quickly measure the relevant EDR parameters on Bluetooth® modules and instruments in addition to performing other tests. In combination with the new EDR option, the R&S CBT Bluetooth® RF tester and the smaller R&S CBT32 are ideally suited to meet these requirements.
The EDR test specification specifies four new transmitter and four new receiver measurements. Fitted with the EDR option, the R&S CBT and the R&S CBT32 allow all measurements – with the exception of EDR C/I performance – to be performed without any external equipment or PCs. With regard to EDR receiver tests, the option supports the loopback test mode in accordance with the specification. Rohde & Schwarz is the first manufacturer of T&M equipment to successfully provide this function. The loopback test mode verifies the receiver sensitivity of an existing Bluetooth® link under virtually realistic conditions.
Like the basic versions before, the R&S CBT and the R&S CBT32 with EDR option feature high measurement speed. Lab tasks can thus be handled more quickly, reducing test times and costs in production. For example, it takes the R&S CBT only five seconds to measure four 2-DH5 and four 3-DH5 packets on three RF channels. During this time, it calculates all measurement results of the test cases "EDR carrier frequency stability and modulation accuracy" and "EDR relative transmit power".
The R&S CBT and the R&S CBT32 with the Bluetooth® V2.0 + EDR option can now be ordered from Rohde & Schwarz.
