; Two output formats are supported: In the default mode,
-; the file output writes I/Q float values (i.e. complex float)
-; to the file. The I and Q samples can take values up to
-; 100000 in absolute magnitude with gainmode FIX.
-; With gainmode VAR, they should never exceed 50000.
-; With gainmode MAX, thet are limited to 32767.

; When the format is set to s8, the output writes I/Q 8-bit
; signed integers, where the magnitude is multiplied by 128/50000
; effectively mapping the gainmode VAR range of -50000 -- 50000
