Re: [Discuss-gnuradio] 3 New Products from Ettus Research
Hello, The TVRX2 sounds very interesting. How are the two receivers mapped to the output? Does each receiver map to a different frequency range on the output? The two receivers would be great for decoding and following trunked radio systems with a dedicated control channel. 73 Eric - Start Original Message - Sent: Mon, 14 Feb 2011 14:38:36 -0800 From: Matt Ettus m...@ettus.com To: gnuradio Discuss-gnuradio@gnu.org Subject: [Discuss-gnuradio] 3 New Products from Ettus Research == We are pleased to announce three new products for use with the USRP family of Software Defined Radios. 1) GPSDO Kit 2) TVRX2 Daughterboard 3) SBX Daughterboard == 1) GPSDO Kit The GPSDO is a GPS-disciplined oscillator, which uses a GPS receiver to steer the frequency of the master oscillator with very high accuracy. This can be used to synchronize devices over large distances without direct connections between them. This frequency becomes the primary reference of your USRP N200 or USRP N210. It also provides a 1 pulse-per-second (1PPS) signal which is used to steer your USRP to within 50 ns of UTC time. The GPS serial output is connected as well, so the exact time can be used by your application. The full functionality of the GPSDO is handled by the UHD, so applications can take advantage of these new capabilities immediately. The master oscillator, an OCXO, is accurate to 25 ppb when there is no GPS signal, so this can be used as a precise reference even if a GPS antenna is not available. The GPSDO kit includes all the necessary cabling to connect it to your USRP N200 or N210. It does not include a GPS antenna, but should work with any commonly available active GPS antenna. The price is $750, and it is shipping now. == 2) TVRX2 Daughterboard The TVRX2 daughterboard replaces the original TVRX. It is a dual receiver covering 50 MHz to 860 MHz. There are 2 entirely separate receivers which can be used simultaneously, either on the same or different frequencies, each with a bandwidth of up to 9 MHz (thus allowing use with DVB-T). The TVRX2 is also MIMO capable, since its clock is synchronized with the master system clock. It is fully supported by the UHD, but not the older drivers, and will work with all of our motherboards. To summarize, the differences between the TVRX2 and original TVRX: - TVRX2 has dual receivers - TVRX2 is MIMO capable - TVRX2 covers a wider bandwidth (9 MHz vs 6 MHz) - TVRX2 is smaller and has plain SMA connectors The TVRX2 costs $200 and will ship at the beginning of April. == 3) SBX Daughterboard The SBX daughterboard is a wideband transceiver similar to the WBX. It covers the 400 MHz to 4.4 GHz frequency range. It has 32dB of transmit power control and output power of 50 to 100 mW (17-20dBm). It is capable of full duplex operation and is fully supported by the UHD, so it will work with all of our motherboards, from the original USRP1 to the latest USRP N210 and E100. The SBX costs $475 and will ship in April. == Thanks for your time, Matt Ettus President, Ettus Research LLC ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio - End Original Message - ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio

I have been waiting for this board! How are the two channels mapped to the USRP2-series devices? Are there two DDCs or do you get two channels using one DDC? juha ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio

BR/ Per If you are using 2 USRPs then the simplest way to do this is to put the GPSDO in one unit and connect it to a second with a MIMO cable. If you need to connect one GPSDO to more than 2 USRPs then you will need to do some cabling of your own. You would need to provide splitters, for example. If you take a look at the datasheet on our website it will be a little clearer. Matt ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
