Turned Off TV Sets Can Jam Signals
Their third harmonics are centered at 567 and 603 MHz. That proved these spurious responses are third-order intermodulation products. So we tracked the source of the third-order distortion, which turned out to be the DTV receiver we failed to turn on.

The rebirth of records
Vinyl requires a rather large helping of equalization (vinyl is terrible at repro'ing bass frequencies due to physics so they cut very low in level then eq'd back up at the phono preamp) and a lot of distortion. Most people who are coming to vinyl …

AM NRSC Measurements
The potential for the generation of intermodulation products should also be considered when making NRSC measurements. The presence of another AM station in proximity, or combined into the same antenna system makes this issue a very real possibility.

Austin, Texas (PRWEB) August 01, 2013

Averna, an industry-leading developer of test solutions and services for communications and electronics device-makers worldwide, announced today the availability of RF Studio for National Instruments Software Defined Radio Platform (USRP), converting the USRP into a portable and cost-effective RF system for the recording and playback of real-world GNSS signals.

National Instruments USRP is an affordable, PC-hosted platform used with NI LabVIEW system design software to build powerful wireless communications systems for research and education. RF Studio is Averna’s proprietary software platform designed to streamline work with real-world RF signals. It provides user-friendly modules for capturing, processing, analyzing, archiving and playing back RF spectrum while also maintaining the signal-recording context.

Working together, Averna and National Instruments teams developed RF Studio for the USRP, an innovative and portable solution to record and play back live RF environments to accelerate RF project work. RF Studio’s LabVIEW compatible plug-in support delivers great value to LabVIEW users as it gives them quick access to a rich toolset for their in-house applications, and supports additional capture sources and customized views.

“RF Studio for the USRP is the only cost-effective and portable product on the market that offers the flexibility to cover a wide variety of use cases, thus making it a very competitive solution for general-purpose RF record and playback,” commented Brendan Wolfe, Director of Market Development for Averna. “We’ve been working very closely with the NI teams to bring this innovative solution to market, and we expect great success from this solution partnership.”

RF Studio for the USRP features:

Record and play back real-world RF signals, up to 40 MHz wide
Capture actual RF spectrum like FM, DAB, GPS, GLONASS, and cellular
Visualize and record weak signals with the Noise Figure view
Advance signal analysis with the Spectrum, Histogram, and Power views
Use simple RF-chain configuration tools to quickly detect and set up the recording environment
DriveView option: Log video, audio and NMEA data at the same time as recording RF

“The combination of RF Studio and the USRP provides a flexible, affordable solution for RF record and playback. Now in addition to prototyping wireless communications systems in LabVIEW, users can test them by reproducing realistic RF environments in the lab,” said Erik Luther, Wireless Communications Group Manager for National Instruments.

Pricing and Availability

RF Studio for the USRP is available now to customers worldwide through National Instruments’ LabVIEW Tools Network. Contact us at sales(at)averna(dot)com for complete details.

It’s getting to be more challenging to receive the JT65B transmissions from the recently launched 4M (Manfred Memorial Moon Mission) lunar payload. The 13-character onboard messages posted from around the world prior to launch were expected to be transmitted this week and will be repeated. On October 25 Ghislain Ruy, LX2RG, of LUXspace said signals from the 4M payload were quite weak.
