Hello everyone!
During power measurement process we can see some messages like:
PM MEAS: ARFCN=8, 55 dBm at baseband, -83 dBm at RF
If I understood correctly, in this example received signal has
-83 dBm (about 5e-12 W) strength before amplifier and 55 dBm
(about 316.2 W) strength after one. It looks like the strength
of amplified signal should be printed as -55 (about 3.2e-9 W),
because 316.2 W is very high value. Am I right? Or is it internal
signal strength representation used by DSP?
С наилучшими пожеланиями,
Яницкий Вадим.

We're talking about a reverse engineered baseband chip, co always take things with a
grain of salt. Your general assumption makes sense that +55dBm is unrealistic.
Please keep in mind that those readings are off by quite a bit as we use no devices
individual calibration tables.
