We have tested 280 GB of random bytes produced by a TL200 with ent, a command line utility that measures entropy. The statistical report is as follows:
Entropy = 8.000000 bits per byte. Optimum compression would reduce the size of this 289304498176 byte file by 0 percent. Chi square distribution for 289304498176 samples is 268.69, and randomly would exceed this value 50.00 percent of the times. Arithmetic mean value of data bytes is 127.5002 (127.5 = random). Monte Carlo value for Pi is 3.141577725 (error 0.00 percent). Serial correlation coefficient is 0.000001 (totally uncorrelated = 0.0).
