<SUBSECTION title="Precision measurements">
The clock frequency of <B>atben</B> can be measured with an accuracy
of about +/&minus; 100 ppm using the program <B>atrf-xtal</B>. <B>atrf-xtal</B>
of about +/&minus; 100 ppm using the program atrf-xtal. atrf-xtal
runs directly on the Ben and measures the duration of packet transmissions.
The transmission time depends on the bit clock which is in turn derived
from the oscillator.
