Hi all,
I'm transmitting a packet to 2.4G
band
using RFX2400 on USRP1 and observed this problem:
Once in a while, the transmission
stops
in the middle of the packet being transmitted.
Does anyone know if 1) there is
any
TX amp control line which is controlled by the FPGA and in what
condition
it toggles,
Any transmit power control will be under control of the
software--the FPGA doesn't make spontaneous decisions about that.
2) if it can happen
when USRP underrun
(uU) occurs
When the host-side underruns the transmitter, it must necessarily
transmit 0s, which effectively turns off the transmitter for the
duration of the underrun.
3) if there is a
schematic for RFX2400
and usrp1 available?
Schematics available here:

I'm using gnuradio 3.2.2.
Thanks,
Thomas
