We got a dab generator TC-2300A in our production line to test dab sensitivity, we play 1kHz signal with the generator while our producats(si4684) cannot found the "station" using dab scanning. with debug message we can see reply bytes from si4684 show RSSI have detected the "station" but with byte 4 FICEER is true, also ACQ = 0, VALID = 0.
1) we have try change the frequency and increase transmitted power even to max, still cannot found.
2) we try our other products using frontier silution can easily found the "station" and streaming out 1khz signal.
3) if change to another generator play recorded files store in its disk, notes, recorded files means record real user case dab staions, no problem.
Now our customer doubt whether this can be a reason cause products pick up less station than frontier, and we also need to get TC-2300A worked to test acoustic features.
please help there, why we cannot found the signal "station", and if there any methods we can try or something we can set to get this generator worked.
Thanks, looking forwards for your reply.
I have a problem with si 32176. The voice recorded from the slic when it's encoded and decoded (pcmu) then played with the slic we hear a noise.
Can you help me
RDS FM radio specification defines the ability to generate emergency warning messages. The RDS spec applies to FM commercial radio. It also implies that an RDS FM receiver will switch to a designated frequency to get that message when the radio transmitter is in range and the beacon is activated. The problem I want to solve is how to program the Si4721 to be a transmitter that can generate an RDS emergency warning message and force the RDS receivers in range to respond to it.
Does anyone know how to do this with the Si4721 radio?
