[Discuss-gnuradio] Portable battery for USRPs
Hi! I have to do a few outdoor experiments with USRPs. Hence I'm looking for portable batteries that can be used for this purpose. After searching a bit, the best option that seems to me is to use 12V heavy duty lantern battery followed by a 12V to 110V DC to AC inverter, which can then be used for the USRP adapter. The combined assembly is still a bit heavy for me. Is there any other better (lighter) option ? Are there any batteries specifically designed to be used with USRPs ? Thanks in advance. regards, Aseem -- Aseem Wadhwa Graduate Student Electrical Computer Engineering University of California Santa Barbara ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
[Discuss-gnuradio] harmonics at 19Khz, 38Khz etc pure tone Transmit
Hi, I'm using usrp2 with WBX daughterboard. I'm transmitting a constant signal 1+j*0. I want to measure the power of the signal at the receiver. But if I look at the fourier transform of the received signal (baseband), in addition to the DC component I find several harmonics at frequencies 19KHz, 38KHz, 57KHz etc upto around 100KHz. This is happening at whatever carrier frequency I transmit, I've tried between 400Mhz-2GHz. What could be the reason for this ? -- View this message in context: http://old.nabble.com/harmonics-at-19Khz%2C-38Khz-etc-pure-tone-Transmit-tp32174397p32174397.html Sent from the GnuRadio mailing list archive at Nabble.com. ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
