DAX I/Q questions

Hi there,
I just started to look at DAX I/Q in FlexLib with the intention to include it in xDAX if possible.
From this I have some simple questions:
- the data format is float normalized to +- 1.0 right?
- does DAX I/Q follows the convention left channel is I and right is Q?? Or for the interleaved data is it IQIQIQ or QIQIQI??
- what is the use the "capacity" and "available" properties?
Thanks and 73

Yes the data is float normalized to +/- 1.0.
Left channel is I and right channel is Q I believe so it should be interleaved in the payload as IQIQIQ
There is a limit to how many IQ streams can stream. I believe capacity and available are supposed to reflect total capacity in "capacity" and available capacity in "available". Today we don't use these but they may be enforced later.0 -
Hi Ed,
thanks.. I had it figured out over the weekend.. One correction though.. The IQ data inside the VITA packet is not float normalized to +/- 1.0 but to +/- 2^15 according to FlexLib and it seems to work if I use it like this..
Thanks and 73
