According to Rohde & Schwarz, it chose the R&S CBT32 due to its high measurement speed. Also, if necessary, to generate and analyze audio signals, the Bluetooth testers can be retrofitted with the R&S CBT B41 option.
LG uses Rohde & Schwarz test and measurement equipment for EDR-specific parameter tests. The EDR test specification stipulates four new transmitter and four new receiver tests. Rohde & Schwarz's CBTgo software offers 18 of the test cases that the standard requires.
