I'd asked the RF boys. 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.
