You're just saving samples from the USRP – there's no info like
"frequency" or "time" attached to those. It's just a very long row of
complex numbers.

Hi,
I have to do timing analysis of individual blocks of gr-ieee80211
I have built my gnuradio with the following
~/rfnoc/src/gnuradio/build$ cmake -DCMAKE_INSTALL_PREFIX=/home/john/rfnoc
-DCMAKE_BUILD_TYPE=RelWithDebInfo -DENABLE_PERFORMANCE_COUNTERS=On -Werror
../
build was successful.

Hi Sumit,

exactly, only GNU Radio needs to be built with that flag – functionally,
it's something that is done in the scheduler, not in the blocks the
scheduler runs.

Dear gnuradio users,
I am trying to use digital_chunks_to_symbols to reconstruct block by block
my QAM modulator.
Please could you give me an idea how to set the constellation points in
Symbol Table field? I can do it with BPSK, QPSK and 8PSK using
constellation[0].points, constellation[1].point
Ok I understood. Now I have a following question.
I did a grep in the build directory
grep -r 'work_time_total' .
And I found that indeed its there as said on https://gnuradio.org/doc/doxyg
en/page_perf_counters.html
It seems a lot of task is already been done ! :)
Then I opened gnuradio-runti
So, the performance counters need to be enabled in your GNU Radio
preferences; I don't think editing the configuration input template
helps, unless you build & reinstall (don't do that). Instead, run
`gnuradio-config-info --prefs` first and check whether PerfCounters are
enabled.
To query these co
Hello Everyone,
Could anyone please tell me why gr-scan gives three different frequency
finding results (2410 MHz, 2412 MHz, 2414 MHz) when I inject only 2412 MHz
signal with -30 dBm power level?
Thanks

Hello,
I have a flowgraph that I made with GRC and modified. All I want to do
with the flowgraph is make it run as a daemon. I understand that if there
are overflows or underflows I'll miss them, that's OK.
I added some basic python code to daemonize my flowgraph:
# Fork once
Okay, I definitely see the signals at +- 1kHz.
And I forgot to mention one other problem.
If I look at the raw data in a frequency sink it's almost a straight
line lying on the frequency axis.
I had to adjust the scaling to +-0.05 to see the symbols. Is this to be
expected?
It seems odd that a

I meant time sink
If I look at the raw data in a TIME sink it's almost a straight
line lying on the TIME axis.

Hello,
I was trying to understand gr-ieee 802.11 wifi_transceiver.grc
I see the youtube video
https://www.youtube.com/watch?v=tAVgsJLM-sc
I believe a single gr-ieee 802.11 wifi_transceiver.grc is running on a
laptop with usrp and communicating with a WiFi card (ath5k driver) of
another laptop
