Tektronix - DPX(TM) waveform image processor technology

: 06 February, 2008  (New Product)
Tektronix has announced the addition of DPX(TM) waveform image processor technology to the mid-range RSA3000B Series Real-Time Spectrum Analyzers. This provides a unique live RF view of the spectrum using the RSA3300B and RSA3408B family models, enabling an unprecedented RF signal discovery capability for a broad range of digital RF applications including RFID, radio communications, and spectrum management. DPX transforms volumes of real-time data and produces a live RF spectrum display that reveals previously unseen RF signals and signal anomalies.
The rapid expansion of digital RF applications has driven the measurement needs of many applications including mobile communications and spectrum management beyond the capabilities of swept spectrum and vector signal analysis. 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, oftentimes, evade detection.

'Tektronix Real-Time Spectrum Analyzers are the first and only analyzers designed specifically to solve problems created by digital RF technologies,' said Rick King, Vice President, Real-Time Spectrum Analyzer product line, Tektronix. 'The addition of DPX technology with live RF from the high performance RSA6100A Series combined with a broad range of application-specific measurements makes the mid-range RSA3300B Series and RSA3408B the best choice not only for the toughest RF discovery and debug problems, but also as an everyday spectrum analysis and system characterization tool.'

With a spectrum processing rate hundreds of times greater than any spectrum analyzer from other vendors, the RSA3300B series and RSA3408B provide 100% probability of intercept for transients as brief as 31 microseconds on the RSA3408B and 41 microseconds on the RSA3300B Series models. Combined with the exclusive ability to trigger on transient signals in both time and frequency domains, the RSA3300B Series and RSA3408B offer unmatched troubleshooting and debug of digital RF designs.

The RSA3300B series is available with either DC-3 GHz or DC-8 GHz frequency coverage. With 15 MHz capture bandwidth and 70 dB Spurious Free Dynamic Range (SFDR), the RSA3300Bs are ideal for use in the design and debug of 3G mobile systems, Near-Field systems (such as RFID and Bluetooth), and narrow to medium bandwidth communications systems.

The RSA3408B with DC-8GHz frequency coverage, 36 MHz capture bandwidth and 73 dB SFDR is tailored for higher bandwidth and dynamic range applications including 3G mobile components and system debug, WLAN and WiMax system design, demanding spectrum management applications and general purpose digital RF debug.

'Many digital RF applications need to detect and analyze RF signals that quickly change frequencies or use complex characteristics,' said David Saar, President, Saar Associates. 'Most spectrum analyzers cannot adequately perform the needed measurements for these applications. Tektronix has addressed these problems by adding robust capabilities for the time domain through its RSA family of Real-Time Spectrum Analyzers, often saving hours or days troubleshooting problems. The unique real-time presentation of live RF signals means that a user will always find a problem signal. This combination of capabilities makes the new RSA3408B and RSA3300B models very attractive for a wide variety of applications.'
