For
GSM
mode,
the
transmit
signal
is
bursted,
so
the
transmit
power
will
appear
averaged
on
the
power
meter
reading.
Note: The MC87xx has a nominal output power of +23 dBm
±
1 dB in
WCDMA mode. However, the value measured by the power meter is
significantly influenced (beyond the stated
±
1 dB output power
tolerance) by the test setup (host RF cabling loss, antenna efficiency
and pattern, test antenna efficiency and pattern, and choice of shield
box).
Note: When doing the same test over the air in an RF chamber,
values are likely to be significantly lower.
