Hi,
Yes, exactly: just a test file. I am still studying
the GSM PHY and I
suspect if I simply position the ARFCNs in different frequencies I
will end up with an invalid GSM signal (that is, it will not be properly
decoded by the Keysight VSA equipment that I have to interface to).
It should work fine. A GSM broadcast channel doesn't include its own
frequency, so you can just take it and position it anywhere (as long
as it's on an actual possible frequency).
In gr-osmosdr the siggen application even has a small hardcoded burst
sequence that's "good enough" for the E4406 VSA to lock onto.
Cheers,
Sylvain
