Hi guys,
I hope you're all doing well.
I'm been searching a lot and I read that if I want to measure the absolute
power ( in W or dBm ) using the usrp_spectrum_sense.py, then I must
calibrate the USRP by injecting a signal of known physical power.
Can someone please walk me through the calibrati
Dear Fikrat,
Feed in a known power, note down the digital power, repeat for another
known power.
You'll get three input power->digital power mappings.
Now, assume the power transfer function is a linear one:
$P_{digital} = G\cdot P_{analog} + P_{noise}$
With the two $(P_{digital}, P_{analog})$
Dear Fikrat,
the physical power depends on your waveform. Generally, the power is
always $P(t) = U(t)\cdot I(t)$, which, thanks to Ohm's law ($U=R\cdot
I\rightarrow I = \frac UR$) is $P(t) = \frac{U^2(t)}{R}$. As you might
know from the basics of electrical engineering, one can represent
harmonic
Hi Fikrat,
no need to apologize :) Just keep the list in CC:, as I did now.
In fact, we're usually pretty happy to meet a few software engineers in
the GNU Radio community. We've got our own experience in writing
efficient algorithms, and our own experts in making things highly
