Now the questions is does the USRP Bandwidth as reported above represent Real or Complex. I would guess they represent complex as well. cheers...<br /> <br />https://en.wikipedia.org/wiki/Sampling_%28signal_processing%29#Complex_sampling<br />Davehttps://www.blogger.com/profile/04519080490067190146noreply@blogger.comtag:blogger.com,1999:blog-8178926928151888432.post-48232417863852248842015-08-02T08:06:00.756-04:002015-08-02T08:06:00.756-04:00With 2 hackrf running full duplex is always better...With 2 hackrf running full duplex is always better then a single board running full duplex. Rx and Tx on a single board at the same time will cause alot of unwanted noise. While the advantage of running 2 hackrf is one board Rx and one board Tx, you'll eliminate this issue. Plus there's alot more benefits running 2 boards then one. e.g 2 microcontrollers, more RAM etc....Anonymoushttps://www.blogger.com/profile/07291144779159415471noreply@blogger.comtag:blogger.com,1999:blog-8178926928151888432.post-48041100542298879242015-08-02T08:00:28.230-04:002015-08-02T08:00:28.230-04:00This comment has been removed by the author.Anonymoushttps://www.blogger.com/profile/07291144779159415471noreply@blogger.comtag:blogger.com,1999:blog-8178926928151888432.post-71665899932328894692015-06-18T04:25:22.384-04:002015-06-18T04:25:22.384-04:0010dBm is 10 miliWatt10dBm is 10 miliWattpe0mothttps://www.blogger.com/profile/10198542685318365908noreply@blogger.comtag:blogger.com,1999:blog-8178926928151888432.post-72110523358577009772015-03-01T23:32:30.989-05:002015-03-01T23:32:30.989-05:00Hi everybody, I have a question about the Bandwith...Hi everybody, I have a question about the Bandwith limit of the platforms, according to Nyquist's theorem Fs >2 Bw. so, the sample rate of HackRF one is 20MSps,<br /> the Bw should be less of 10MHz.

See http://ossmann.blogspot.com/2012/06/introducing-hackrf.html<br /><br />The writeup (which currently talks about how the hackRF uses a "hodgepodge of chips each designed to operate in a certain portion of the spectrum, which are then connected by at least six radio frequency switches, [...] Hopefully all of these added components will not add too much noise to the system.") misrepresents the actual design of the hackRF. It does use a three chip solution to achieve the 10MHz to 6GHz rated tuning range (the article needs updating, the current spec is 10MHz at the low end instead of 30MHz: http://greatscottgadgets.com/hackrf/), and the three chips are designed to operate in certain parts of the spectrum, that's technically also true.<br /><br />But all of the three chips are always used no matter what part of the spectrum the radio is tuned to. The RFFC5072 mixer downconverts or upconverts the 10MHz-6GHz input signal to a a 2.4GHz IF. Using such a high IF (placed in the middle of its 10MHz-6GHz tuning range) allows tuning over such a large range cost-effectively. There are many low-cost, relatively high-performance chips designed to work with 2.4GHZ ISM signals in consumer applications. Of these, the hackRF uses the MAX2837 to downconvert from the 2.4GHz IF to near baseband, which is then digitized by the MAX5864 (which can also function as a DAC for transmitting, and the whole chain can be used in reverse).<br /><br />In terms of cost, the single-chip AD9361 solution used in the USRP costs $175 just for the chip itself, even in 1k quantities. This is more than half the cost of the whole hackRF. Each of the three chips in the hackRF solution are less than $10 each in similar quantities, and together allow tuning a similarly wide frequency range.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8178926928151888432.post-6098511372909047172014-04-26T02:46:43.851-04:002014-04-26T02:46:43.851-04:00I am using USRP B210...In the specification sheet ...

At student level, dishing out Rs. 1,40,000 (INR 72000 on each of the two B100 bundles, in India) is practically not possible. So, we have come across BladeRF and now, HackRF. So, what I want to ask you is "Is BladeRF programmable, just like USRp is along with its daughterborads, and inturn can it be used to program a cognitive radio by myself"Abhijith Yadavhttps://www.blogger.com/profile/02642101739573539681noreply@blogger.com
