NRA-2500, NRA-3000 and NRA-6000 Narda Remote Spectrum Analyzer Measurement, analysis and monitoring of RF signals 19" rack mountable Spectrum Analyzer for remote controlled measurements and analysis of electrical signals ranging from 9 kHz up to 6 GHz. Application-oriented operating modes with resolution bandwidth (RBW) up to 32 MHz Spectrum Analysis mode with Wideband FFT and Channel Monitoring Multi-Channel Power mode for fast transponder evaluation (optional) Level Meter mode with True RMS and PEAK detection (optional) Scope with I/Q Data (optional) Easy integration and remote control of NRA into measurement environment via Ethernet Simple and convenient easily understood commands Outstanding remote documentation with examples and Demo Software High speed measurement Fan-less design for silent, continuous operation Compact size saving 1.75" (1RU) high INTRODUCTION The digital design of the NRA Analyzers is based on a smart combination of the super heterodyne principle with leading-edge FFT analysis and trigger functions. It captures pulsed and random signals and is ideal for short- and long-term observation of all types of RF signals. Evaluation functions and signal integration capabilities reduce the amount of raw data and increase measurement speed and performance. Subject to change without notice

THE NRA FAMILY The NRA family is an application orientated product concept. Each NRA type is aimed at a specific RF signal measurement task. The compact size and wide range of remote operation facilities make integration with 3rd party software for monitoring & surveillance applications both fast and straightforward. The devices use ASCII based commands for all the measurement tasks needed for long-term monitoring, such as stability of carrier/band power. The measurement data are also available in binary format to optimize the speed of communication. To help you with programming, the NRA offers...

NRA AND ITS APPLICATIONS Satellite newsgathering NRA is particularly suitable for use in satellite newsgathering trucks for SD or HDTV transmissions (D-SNG). Its compactness and wide variety of remote operation possibilities make for quick and straightforward integration. When using NRA with 3rd party software for control & monitor (C&M) applications, ASCII based commands can be used to perform all the measurement tasks needed for antenna peaking and satellite tracking, as well as for transponder and carrier monitoring. The LNB Control variant of the NRA-3000 provides a space-saving solution...

Operation and monitoring systems The compactness and wide range of remote operation functions of the NRA allows quick and straightforward integration with operational support software (OSS) or comparable control & monitor (C&M) systems. Measurement tasks can be carried out with the analyzer using the simple ASCII-based command set in conjunction with 3rd party software. The broad range of options means that the cost of the analyzer can be exactly tailored to specific needs and / or the available budget. NRA provides straightforward remote performance and condition analysis for different signals....

OPERATING MODES The main operating mode of the NRA provides powerful spectrum analysis. Other operating modes are available as options, so the device can be optimally configured for specific measurement tasks. It is also possible to add features at any time, so the NRA is a future-proof, versatile measurement solution for a diversity of applications. SPECTRUM ANALYSIS Spectrum Analysis mode covers a wide frequency range from 9 kHz to 6 GHz, depending on the version chosen, and features finely adjustable resolution bandwidths from 10 Hz to 20 MHz. The input attenuator is adjustable in 1 dB steps...

SCOPE and IQ DATA (Option) Scope mode (zero span operation) provides an oscilloscopic time domain analysis. Almost all signal details can be made visible in this mode to allow rapid classification. The minimum resolution time of 32 ns even allows analysis of high-speed data transmissions or pulsed signals such as radar. A top sweep time of 24 hours allows full-day power monitoring of a single carrier. Extensive trigger functions allow for triggering and subsequent monitoring of burst signals including a pretrigger view. RF signals can be completely described by I/Q data. The I/Q demodulated data...
