Nobody can recall exactly, they do it more than two years ago, but they did it with MXA Signal Analyzer which measures frequency error. They do not spent too much time on it beacuse if you have 5ppm quartz generator then the precision of carrier frequencies is guaranteed by design. Most problems in ETSI is out-of-band radiation pattern which it defines in absolute values in contradistinction to FCC. Regards, Alex.
