-; The file output writes I/Q float values (i.e. complex float)
+; 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.
+;format=complexf
+;
+; 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
+; to -128 -- 128. For other gainmodes, use the digital_gain setting
+; to make sure you don't create clipping.
