Capturing IQ Data With NRA And IDA Technical Note

2014-03-14 14:50:28| rfglobalnet News Articles

With the Scope/IQ option, the NRA and IDA instruments allow you to generate IQ data from the received data and display, demodulate, and store them, and transmit them block by block or as a continuous stream via a remote interface. What, though, is the significance of this I/Q data? What are they used for? And, how are they obtained using NRA and IDA?

IDA says operators cannot block OTT services

2014-03-03 00:10:00| Telecompaper Headlines

(Telecompaper) Telecommunications providers in Singapore must give mobile consumers access to web content and apps. The Infocomm Development Authority (IDA) made the declaration after the CEO of SingTel asked regulators to allow operators to charge over-the-top (OTT) service providers for the use of their networks. The IDA will be closely monitoring developments in the OTT market and track discussions between operators and OTT players, ZDNet reports citing an IDA spokesperson. IDA currently assumes the position that consumers should have access to all legitimate internet content and applications. Service providers may not block or impose restrictions to make certain legal web content inaccessible or unusable. Traffic management practices are also not allowed.

The Signal Beneath The Signal: IDA 2 Makes Payload And Interference Signals Clear

2014-02-10 11:00:32| rfglobalnet Downloads

Detecting RFI, revealing the causes of interference, locating unauthorized transmitters – all these are tasks performed by modern direction finding equipment. Spectrum analysis and time domain displays give much information about the type of signal, but they don’t reveal everything. They are limited to recording the amplitude versus frequency and / or versus time, and often lose information due to display compression. The full picture is only seen when the measured values are recorded without compression and separated into their real and imaginary components, usually referred to as the in phase and quadrature components, or I/Q for short.
