Hi Matt --
Got things built and usrp2_fft.py working (more or less).
Just FYI, on my 3 year old Thinkpad T42 laptop with 1.6 GHz Pentium M, I
can display about 4MHz of spectrum (decimate 25) with good results.
Trying to show 5 MHz works, but occasional flakiness results. Anything
beyond that causes either very jerky display, or lockup.
Using nice -10 helps a bit. I don't know if this is consistent with
what others have seen. Next step is to build on my Athlon X64 in the
basement to see how that does.
Hello,
I have a Z60t with a 1.7 GHz Pentium M and found some overruns and
occasional hiccups with the USRP1 at 8 MHz depending on what processing
is done on the computer.
2. The usrp2_fft.py program is pretty nice, but changing the frequency
in the input box doesn't seem to work -- when I type something in, I get
an "OK" at the bottom left of the window, but the display freezes and
nothing further happens.
Matt mentioned at DCC that changing frequency does not work yet.
