Hi all,
We're currently working
with a BasicTX daughterboard attached to a N210 USRP. We are using both
outputs of the BasicTX in quadrature (I on one channel, Q on the other).
The problem we are running into is that the output power of the BasicTX
board seems very low. Looking at it on an o-scope, we are seeing around
166mV RMS on each channel, which seems lower than we would expect.
We
are using GNURadio Companion to transmit these waveforms, and it is a
very simple setup. A single "Signal Source" block generating a sine wave
into a "UHD: USRP Sink" block. The "amplitude" value is at it's near
max without clipping in the ADC and since the daughterboard has no gain
elements, "gain" does nothing, so we're kind of at a loss here.
Any help is appreciated.
