 [fileoutput]
 ; 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.
+; 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 810000 in absolute magnitude with gainmode FIX. With
+; gainmode VAR and FIX, they should never exceed 50000.
 ;format=complexf
 ;
+; When the format is set to complexf_normalised the maximal
+; amplitude written to a file, is the digital gain +-10%.
+;format=complexf_normalised
+;
 ; 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
