Reply To: Flirting IQ stream

Hello Justin
Thank you for answer.
With “douwsampleFactor” I understood. It is clear from API Manual.
For me interested third parameter from bbConfigureIQ. It is “bandwidth”

bbConfigureIQ(int device, int downsampleFactor, double bandwidth)

I tested receiving IQ stream for GSM. So I think that in BB60C exist digital filter.
Examples:
I can synchronization with GSM signal if I use:
bbConfigureIQ(int device, int downsampleFactor, 200000)
and I cannot do it if I use
bbConfigureIQ(int device, int downsampleFactor, 2000000)
Because I have mixed with others GSM channel.
But if use “bandwidth” = 2000 I can synchronization with GSM signal. So I don’t fill difference between 2000 and 200000.
Probably parameter “bandwidth” has some limit for low value.
Can you give me some description?
Because I cannot find it in API Manual.
