SimGEN: What is the format of the LAAS RS232 output?
It is not necessary to have the GSS4150 LAAS signal generator to get the LAAS data stream.
The GSS4150 is required for an RF output. Please contact
for further information on this feature.
The LAAS output is streamed to the defined COM port and output there using the RS232 (RS-232) protocol.
The datastream is also saved locally in the file called rsdata.dat
The bit-stream data file of the data transmitted on the RS232 output port, a 256-byte block for each frame.
The bit-stream starts with the first bit of the first Message Block Header and ends with the last bit of the last Message Block CRC.
This file does not have the Training Sequence or Application FEC bits and is not ‘bit scrambled’.
