No change in size ,  16 September 2016
The 32-bit version performs as good as the hardware lock-in. For some reason, the hardware lock-in PSD noise increases for higher frequencies, and for the 32-bit FPGA lockin it doesn't. The 32-bit version has 50 times smaller noise level than the 16-bit version.
