Tektronix real-time spectrum analyzer aimed at digital RF explosion
September 8, 2006
Tektronix has announced the RSA6100A series of real-time spectrum analyzers that provides a combination of real-time performance, capture bandwidth and dynamic range to meet the needs of a broad range of digital RF applications.
The analyzer’s DPX waveform image processor technology transforms volumes of real-time data to produce a live RF spectrum presentation that reveals previously unseen RF signals and signal anomalies. Live RF is achieved by improving the spectrum measurement rate nearly 1,000 times compared to the fastest swept spectrum and vector signal analyzers (VSA).
Digital RF signals carry complex modulation and change from one instant to the next, hopping frequencies, spiking briefly and then disappearing. These transient and time varying transmission techniques help RF devices avoid interference, maximize peak power and evade detection.
Test instruments for digital RF require wide bandwidth with high dynamic range, fast signal capture and the ability to fully correlate the time, frequency and modulation domains. The first offerings in the new RSA6100A series of real-time spectrum analyzers — the 6.2GHz RSA6106A and 14GHz RSA6114A — provide 110MHz real-time bandwidth simultaneous with 73dB spurious-free dynamic range.
