Narda NRA-3000 and NRA-6000 remote spectrum analysers

The NRA-3000 and NRA-6000 remote spectrum analysers from Narda now provide uninterrupted I/Q data as a real-time stream. At the same time, the number of samples for spectrum analysis has been increased to over 600,000.

The ‘Scope and I/Q Data’ option for the analysers delivers the data from signal sequences separated into the real (or in-phase) and the imaginary (quadrature) components. Coverage is uninterrupted up to a channel bandwidth of 400 kHz.

The data are available as a gapless stream via TCP/IP or UDP. The NRA transfers the data in blocks of up to 250,000 points for channel bandwidths of up to 32 MHz. Remote commands similar to plain text allow for further evaluation using add-on software and hardware analysis tools.

Additionally, the NRA is suitable for use as the RF frontend (DSP) in the satellite communications range, eg, in measurement and control systems, where constellation diagrams and quantities such as MER (modulation error ratio), EVM (error vector magnitude) or Eb/NO (energy per bit to spectral noise density) are required.

The NRA provides authorities, measurement service providers and transmitter operators - especially teleport operators - with the means to monitor the spectrum locally or remotely to check the signal quality, to determine interference and to make use of or lease unoccupied frequency gaps (multicarrier spectrum filling).
