I searched threads here and couldnt pick out one where the below was discussed- if you know of any, please hit me with a link to the thread ?
I noticed an interesting phenomena when running gain scripts. During a reboot when returning the config to -10 ( AGC) the stats momentarily soar, hitting over double the message rate and plane count- then stats zero out and climb back to a lower, more expected level.
Its as if the dongle gain throttles way up to the max and then cuts off and allows gain to build back to some software determined level. However, there is no manual gain setting that can attain those message rates. I don’t believe that the current versions support the MAX command.
So that makes me wonder if the 49.6 gain setting we have access to is lower than what the card is actually capable of by a good margin. Also, it appears that the software is using some unknown to me algorithm to set a gain threshold, perhaps based on signal to noise ratio or just a plain ole clip level. In any event its clear that AGC is not bound by the 49.6 limit, but I have no idea what gain it actually uses.
