The "Scope and I/Q Data" option on the NRA-3000 and NRA-6000 analyzers displays signal data, separating the real (in-phase) and imaginary (quadrature) components. Coverage is continuous up to a channel width of 400 kHz. Data is available via streaming, TCP/IP, or UDP. The NRA transfers data in blocks of up to 250,000 points for channel bandwidths up to 32 MHz. Remote text-based commands are available for further evaluation with other hardware or software tools. The NRA can also be used as an RF frontend (DSP) in the satellite communications field, for example, in measurement and control systems that require constellation diagrams and the measurement of parameters such as MER (modulation error rate), EVM (error vector magnitude), or Eb/NO (energy per bit to noise spectral density ratio).
The number of samples (bins) in spectral analysis mode exceeds 600,000, allowing the measurement of a 6 GHz spectrum with 10 kHz separation between bins, without the need to tune to multiple different ranges. Users can also select the desired result type (instantaneous value, maximum value, average value, etc.).
The NRA provides authorities, service providers, and operators—especially teleport operators—with the necessary tools to monitor the spectrum locally and remotely (in accordance with ITU-T recommendations), verify signal quality, determine interference, and utilize or lease unoccupied frequency ranges (multi-carrier radio spectrum management).
The NRA family
of remote spectrum analyzers covers the frequency range from 9 kHz to 6 GHz, with resolution bandwidths from 10 Hz to 32 MHz. They can be integrated into virtually any measurement and verification environment thanks to their Ethernet interface (100BASE-TX) and remote control commands in plain text (ASCII). Large amounts of data can be transmitted quickly in binary format. Application-oriented operating modes include: spectral analysis (spectrum), simultaneous power measurements on different channels (multichannel power), peak and RMS level measurement (level meter), and capture of the time-domain characteristics of a signal (Scope and I/Q data).
All NRA devices are 1U high and weigh less than five kilograms. Power consumption is less than 25 VA, meaning they operate silently without the need for forced ventilation. They are ideal for use with mobile systems and in confined spaces.
IDA-3106 interference analyzer that also locates impulse signals
Narda Safety Test Solutions has added new features to the IDA-3106 Interference and Address Analyzer that allow for even faster and more reliable location of interference and unknown signals. It is possible to locate pulsed or sporadic signals using a scan...
