Re: [Discuss-gnuradio] calibrating USRP

2013-07-10 Thread Marcus D. Leech
I think that i am a little bit confused with calibration. Is there any way to determine the gain of the circuitry in front of the ADC? Is it correct enough to say that power level at the input of PGA in front of ADC is just ((sampled_value*Vp-p)/2^12 ^ 2 ) / Rinputpga? The total gain in fron

[Discuss-gnuradio] Linker error

2013-07-10 Thread Weigel, Sebastian
Hi GNURadio-Community, I tried to install GNU-Radio 3.7 on Ubuntu 13.04. After getting all the dependencies with the instructions from http://gnuradio.org/redmine/projects/gnuradio/wiki/UbuntuInstall "cmake" worked, but when I tried "make" I got an error message: Scanning dependencies of target

Re: [Discuss-gnuradio] Question about Cycle Detection in GNU Radio

2013-07-10 Thread Tommy Tracy II
What I'm trying to do is this: 1. The Root Router receives data from an input flow graph, packages it and sends it to its children in a balanced manner. 2. The Child Routers receive data, and, as a Source block, streams the data to the Child's flow graph. The resulting output needs to be return

Hello All, I've been trying to connect a USRP N200 to a PC, however, I had no success. During some seconds, the connection is established, I do can ping the IP 192.168.10.2 and find the device by uhd_find_devices command, but then it dies. The LEDs D and F remain on. I could not even install the

[Discuss-gnuradio] AttributeError: 'function' object has no attribute 'to_basic_block' ? (GR 3.7.0)

2013-07-10 Thread Monahan-Mitchell, Tim
I've stepped up to GR 3.7.0, re-used gr_modtool to freshly re-create my OOT module, everything builds, tests, installs OK. GRC has my OOT blocks listed and I can put them on my flowgraph. One of my OOT blocks is a function that takes in shorts and outputs shorts (a 1-to-2 interpolator). I have
