Do I offset tune with the xb200?
Posted: Sat Feb 27, 2016 2:57 pm
I have a GNURadio flow graph (recent git pull) with a HackRF One as the source and a BladeRF x115 as the sink with an x200 to transmit in the 131MHz range. The purpose of the HackRF One is it came first. I am trying to transmit a signal within a screen cage to debug my blocks.
I have an RTL SDR within the cage running GQRX. It indicates nothing is being transmitted by the bladeRF. I have instrumentation that indicates packets are going to the bladeRF. A couple of questions come to mind.
1) I see nothing in the documentation that indicates I need to offset tune when using the xb200. Is that true?
2) Does the Rx side of the bladeRF need to be active in order for the Tx side to work?
3) What verification mechanism is available to indicate the bladeRF is transmitting? An LED, perhaps?
My configuration string in GNURadio is:
bladerf,xb200=144M,verbosity=info,fpga=/usr/local/share/hostedx115.rbf
My default VG1 setting is -25 and VGA2 is 5.
TIA
