Hi, When I ask my RFX400 to tune a frequency for example 438.600MHz I get the following output.
A: Flex 400 Tx MIMO B r.baseband_frequency = 442000000.0 r.dxc_frequency = -3400000.0 r.residual_frequency = -0.381469726562 r.inverted = False This means that the synthesiser tunes to 442MHz and in the FPGA the base band signal is frequency translated to -3.4MHz? Thus the output is on frequency at 438.600MHz. Have I spelled that out correctly? I am just trying to get a picture of how the system works to tune all the frequencies that I may throw at it. Also questions about the WBX: How come the RFX400 is now depreciated in favour of the WBX but the rest of the RFX series are not and seem to be covered by the WBX frequency range? The connector J101 pictured on the WBX on the image available on the ettus website; is that so that a SMA connector can be directly attached to the receiver? Thus eliminating problems relating to cross talk in the little rf switches on the grand-daughter board.
