For the problem related to the different amplitudes of 2 Tx RFX2400 transmited signals

Hello,

I have an issue with the amplitudes of two transmitted signals. I was
trying to implement 2 TX and 1 RX(MISO) and I found the problem that
these two RFX 2400 daughter boards that I am using as transmitters gave
me noticeably different amplitudes of the tranmistted signals. I changed
my motherboard(At school, there are at least 3 USRP), but it had an
exact same problem. Even, when I implemented 1 TX and 1RX(SISO), the
amplitude of transmitted signal from each RFX 2400 was not the same. My
amplitude value in my python code was exactly same BTW. Does everyone
has the same issue? Is there anything that I can do for this problem
other than approximately adjusting my amplitude value in my python code?
Please tell me if you or anyone has the answer.

Thank you,

Joon Kim

It’s not unusual for analog gain chains to have small gain variations in
them. Just a fact of
life.
