There is no option on this scope, I double-checked. Maybe the standard -A options aren't
listed there. I do have FFT and it would stand to reason that this TDS544A only has 
standard options since they are very cheap where I work.

Firmware is V3.4e
Serial number is B010956
Date code of most ICs including NVRAM is 1993

Didier, could you please add that info to the file somehow?

Thanks,

ST
