[Discuss-gnuradio] run time flow graph switching

2008-04-02 Thread TomasOMaille
Hello, I've seen a few threads touching on real time flow graph switching but I haven't been able to implement a solution to my particular problem. Setup: 2 USRPs + 4 RFX900 boards + 1 RF Source at 864MHz (European SRD band) Task: I want to run three specific programs one after another in

Thanks Matt, Your board was already configured properly and you don't need to do any of this. Glad I didn't stumble in with a soldering iron. Tomas -- View this message in context: http://www.nabble.com/RFX900-and-Clocking-Notes-tp15202177p15264312.html Sent from the GnuRadio mailing list

[Discuss-gnuradio] RFX900 Transmit Power

2008-02-04 Thread TomasOMaille
Hello again, I have another question regarding the RFX900 daughterboard. I am trying to get a sense of the power transmitted by the RFX900 board in order to avoid breaching European communication regulations. Ideally a figure for the equivalent isotropically radiated power (EIRP) would be

[Discuss-gnuradio] RFX900 and Clocking Notes

2008-01-31 Thread TomasOMaille
Hello, I am reading the Clocking Notes in order to set up a coherent 2 antenna system. My setup is a USRP Rev 4.5 and two RFX900 daughterboards dated 3-10-2006 Step1: I want to disable the RFX900 clocks so I need to Move R64 to R84, Move R142 to R153 which looks straight forward. Step 2:

[Discuss-gnuradio] Bus widths and data rates

2008-01-30 Thread TomasOMaille
Hello, I have been trying to understand the tx and rx data paths through the AD9862 and the FPGA (standard configuration). RX side: - The two ADCs of the AD9862 push data onto two 12 bit buses - After the FPGA MUX the 16 bit I/Q signals pass into the assigned DDC - Are four extra bits
