Easy-to-Use Ultra-Wideband Spectral Analysis for Performance Real-Time Oscilloscopes


Spectral + Down Conversion Analysis Mode: Ultra-Wideband Radar LFM “Chirp”

Analysis and verification of Ultra-Wideband microwave, optical and electrical signals require more real-time bandwidth and capture time than is possible with spectrum analyzer-based solutions. Supporting acquisitions up to 200 Mpts at 50 GS/s on four simultaneous channels, the DSA/DPO70000 Series oscilloscopes provide an ideal platform for working with these signals.

DPX® and pinpoint triggers help you quickly discover and capture the time and amplitude variations of live data. Time gating cursors on the scope and an integrated packet/pulse finder in the application help isolate specific signals in the presence of other traffic. Real-time spectrograms spanning the full single-shot bandwidth of the instrument quickly visualize the frequency content of any signal as a function of time. A user-definable resolution bandwidth allows the spectral displays to be optimized for the signal being studied.

Digital Down Conversion of captured RF data is fast and easy using visual cues from the Power Spectral Density display. The down-converted frequency span of interest, to 20 GHz real time, may be exported for further analysis in tools such as RSAVu and MATLAB*1.

A fully-integrated WiMedia analysis mode makes quick work of capture, analysis, verification, and documentation of WiMedia MB-OFDM waveforms.

RSAVu Analysis of the Ultra-Wideband Waveform

Ultra-Wideband microwave up to X band and Ku band is directly captured with the DPO/DSA70000 oscilloscope and may be analyzed using Tektronix RSAVu.

Lower frequencies can be captured directly to 3.5 GHz with the DPO7000 oscilloscope.

RSAVu offers the same demodulation and analysis capabilities included on the RSA3408 software option suite. Analysis includes pulse parameters, frequency, phase and amplitude vs. time in the free RSAVu base software. Analog Modulation Analysis includes IQ vs. Time, AM Depth, FM Deviation, PM and Pulse Spectrum. Time Analysis includes IQ vs Time, Power vs. Time, Frequency vs. Time, CCDF and Crest Factor. Pulse Analysis includes Pulse Width, Peak Power, Ripple, Pulse Repetition Interval, Duty Cycle, Pulse-to Pulse Phase, Frequency Deviation, Channel Power, OWB, and EWB.

WiMedia PHY Test Specification 1.2 Analysis Mode

The WiMedia analysis mode provides a simple, easy-to-use interface for analyzing these complex MB-OFDM signals. Through automatic packet, TFC and data rate detection, setup is greatly simplified and analysis time is minimized. With support for all six band groups (spanning 3.1 GHz to 10.6 GHz), all 10 time frequency codes, and all eight data rates, Tek UWB provides a complete solution for those working with WiMedia waveforms.

Rapid visualization and debug is supported with a wide array of plots, including Spectrograms, Power Spectral Density, QPSK/DCM Constellations, EVM-vs-Symbol, EVM-vs-Subcarrier, Common-Phase-Error-vs-Symbol, and Voltage-vs-Time plots. Interactive browsing of constellation data by symbol and subcarrier using cursors provides coupling between plots and helps pinpoint signal problems.

Measurements are performed on a packet-by-packet basis according to the WiMedia PHY Test Spec 1.2, and include EVM, Preamble Sync Cross Correlation, Frequency Tolerance, Adjacent Channel Power Ratio, Spectral Mask Testing, and Relative Power Ratios. PASS/FAIL test conditions are reported for each measurement, as well as for the total test suite.

Modulation results are accumulated in a database which may exported for quick historical documentation. In addition, a detailed report for individual waveforms may be created using the integrated report generator. These reports provide a convenient mechanism for quickly documenting configuration information, measurement results, and plot images in a single file, simplifying document organization and distribution.

Choosing the Right Scope for the Job

TDS/DPO/DSA oscilloscopes with a single shot bandwidth of 7 GHz or greater are required for capturing WiMedia signals in band group 1. Analysis of higher band groups requires oscilloscopes with correspondingly higher bandwidths. Coverage for all six WiMedia band groups will require a single shot bandwidth of at least 14 GHz.

Analysis of radar signals through X band and Ku band calls for real-time bandwidths beyond 16 GHz. The DSA72004 oscilloscope with single shot bandwidth of 20 GHz and deep 200 Mpts record length provides the greatest flexibility for analyzing such high-speed signals.

Measurements for all six WiMedia Band Groups, all ten Time Frequency Codes (TFCs), and all eight WiMedia Data Rates
  • Error Vector Magnitude, peak and RMS
  • Frequency Tolerance, by band
  • Preamble Cross Correlation, by symbol
  • Adjacent Channel Power Ratios (ACPR12, ACPR13, ACPR21,ACPR23, ACPR31, ACPR32) between each band within a band group
  • Spectral Mask testing, by band
  • Relative Power measurements, by band
  • Decoded PLCP Header Information
  • PASS/FAIL conditions for compliance test
