[Discuss-gnuradio] Follow-Up Question: Enabling Rx-A and Rx-B on a single daughterboard

I would just like to make a follow up question. Have you enabled Rx-A and Rx-B simultaneously on a single Basic Rx daughterboard? If so, how did you do it? I would just like to receive signals from both ports of a single Basic Rx Daughterboard. Thanks!

Re: [Discuss-gnuradio] Question: Setting Rx-A and RX-B Daughterboard on simultaneously

Unfortunately, it didn't. I would like to know how to get data from the two sides of a SINGLE Rx Daughterboard. Currently, I have a daughterboard at the RXA side of the USRP. I want to get data from both input ports of that single daughterboard. Is this possible? Thanks!

[Discuss-gnuradio] Question: Setting Rx-A and RX-B Daughterboard on simultaneously

Hi all! Is it possible to set both the Rx-A and the Rx-B (of the BASIC Rx daughterboard) to ON while at the same time allowing I and Q sampling? How will this be done? Thanks! ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org

Re: [Discuss-gnuradio] Problem: Accessing RX-B of the basic Rx daughterboard

Hi! Thanks for your reply. It was helpful! However, I have another follow-up question. So, basically I won't be able to access RX-A and RX-B simultaneously since I have to set the MUX everytime? Is this correct? Thanks! ___ Discuss-gnuradio mailing

[Discuss-gnuradio] Problem: Accessing RX-B of the basic Rx daughterboard

Hi! What command should I use when I want to access the received signals at port RX-B of the Basix Rx daughterboard? I have tried using usrp.source_c(1,my_block) but then an error results saying that I cannot find usrp 1. What I intended with that command was to access RX-B of the BASIC Rx

[Discuss-gnuradio] Problem: passing output to gr_vector_sink_c

Hi! I have a problem passing outputs from my signal processing block to a gr_vector_sink object that I have created. I implemented my signal processing block using the standard C++ class template called complex. I particularly used the complexfloat type. I was just wondering whether this would

[Discuss-gnuradio] Question: How to read file contents

Hi! Since no one has responded to my post regarding my problem on reading a file. I will post another message regarding this. But instead, I'll ask a very basic question. How do you read contents from a file using GNU Radio blocks? I always get an empty list when I try to run the code that I

Re: [Discuss-gnuradio] Question: How to read file contents

Hi! Thanks for your reply! Yes, the file contains a string representation of floats. So I suppose that the file should contain a binary representation of floats? And, yes I did start my flow graph. I would like to apologize for not including it in my post. But, rest assured that I ran my flow

[Discuss-gnuradio] Problem: Reading a file

I have a problem reading an ascii file. I tried reading it using gr_file_soucrce and extracted it using gr_vector_sink_f. Then I tried extracting the data by using object.data(); or in short, by using its data member. Unfortunately, I always get an empty list. Why is this so? Here's a snippet of

[Discuss-gnuradio] Question: Possible Problems with SWIG

Hi again! I'm trying to implement a signal processing block that makes use of classes that I personally defined. To be exact, I included a class that has the capability to perform Matrix and Complex Algebra (elem_matrix). The source codes compiled well (after following the howto example).

[Discuss-gnuradio] Question: gr_float_to_complex

Hi again! I have a question regarding the use of gr_float_to_complex block. Unfortunately, Doxygen didn't show the implementation of such a block. What I wanted to know is how gr_float_to_complex implements float to complex conversion. I could only guess that it treats the first number as the

[Discuss-gnuradio] Re: question on using gr.file_source

Hello again! I still have the same problem. Unfortunately, I still can't make gr.vector_sink to work. I mean, how would it know that I just want to extract data from a particular source. Let's say I have these codes: yrx1_real = gr.file_source('arguments omitted') yrx1_imag =

[Discuss-gnuradio] Question: gr_dd_mpsk_sync_cc

Hi! I have another question. Can the gr_dd_mpsk_sync_cc block demodulate BPSK? Also, is there anything I should know before using this block (like warnings on what should not be done since it may result in erroneous decoding of the messages)? Thanks!

[Discuss-gnuradio] Question: Array of complex numbers as input

Hi again! I am trying to make a signal processing block that uses an array of complex numbers at its input. I was just wondering whether input_items can support this. I was told that the input_items are simply plain old data. So if I cannot pass an array of complex numbers as an input argument,
