Carrier test in direct test mode(DTM)

[Jusang Kim]

Hello

I want to clarify the exact meaning of the carrier test or unmodulated signal in DTM. In carrier test mode, DUT transmits 0xFFF....FFF which means all one pattern. All one payload data in the packet generates only one frequency in GFSK modulation.

Is it the reason why you call it the carrier test or unmodulated signal in the chip specification ?

Not sure I understand the question. But you can find details about the Vendor Specific packet payload here.
