Tektronix brings spectrum analysis to scopes

Tektronix has launched SignalVu, which is vector signal analysis software for its DPO7000 and DPO/DSA70000 series oscilloscopes.

I spoke to Jim Taber, Tektronix's Senior Product Planner, about this new release recently. He explained it this way, “We have taken the analysis engine of our real-time spectrum analyzer and placed that on the user interface of the scope.” This means that you can drive the scope like a traditional vector signal analyzer (VSA), setting frequency, power, and span. The software is designed to give you quick validation of common tests including: RF measurements, pulse parameters, modulation analysis, and automated tests.

The SingalVu interface brings time overview, drag-and-drop measurements, pan-and-zoom controls, correlated markers, and automated pulse measurements to a scope that already features, a 20GHz analog bandwidth, 50 GS/s sample rate, 500 MS memory, and advanced triggering (Tek scopes over 1400 different combos for trigger configuration).

With this new analysis package, users should be able to isolate problems that are time-correlated with multi-domain markers. The aim is to provide designers with better results using less equipment, and the scope offers the benefits of inherently good dynamic range and powerful triggering capabilities. Applications include wideband radar, high data rate satellite links, spectrum management, and frequency hopping communications.

Tektronix designed the SignalVu software to integrate spectrum analyzer and digital oscilloscope functionality. This means that users do not have to hop between modes in order to completely analyze their signals. So, SignalVu controls all scope acquisition parameters such as record length, vertical scaling, and sample rate, and it allows users access to all of the scope's powerful triggering capabilities. Once triggered, SignalVu processes the acquisition for analysis in multiple domains. In addition, multiple measurements can be made without a need to recapture the data. All signals in an acquisition bandwidth are recorded into the oscilloscope's memory. Up to four channels can be captured simultaneously and each can be independently analyzed by SignalVu software.

Besides spectrum analysis, users have access to spectrograms that display both frequency and amplitude changes over time. Time-correlated measurements can be made across the frequency, phase, amplitude, and modulation domains. Here are some good examples of measurements:

  • Analyze frequency hopping radios, viewing agile behavior in time, frequency, and amplitude, understanding the spectral behavior over time
  • Analyze wideband radar, making direct measurements of Ku-band signals across wide acquisition bandwidths. 20GHz of analog BW allows you to measure up to 18GHz without using external hardware. Automated pulse measurement feature can characterize up to 10,000 pulses and perform 21 different parameter measurements on each pulse.
  • Analyze wideband digital communications, finding difficult problems more quickly with time-correlated, multi-domain analysis of wideband modulated signals. You can find a problem in one domain, and analyze it in the others because the markers go from one screen to another.

SignalVu vector signal analysis software is now available for order on all DPO7000 and DPO/DSA70000 series oscilloscopes. The basic package is SignalVu Essentials that provides eleven core measurement and analysis capabilities. U.S. MSRP for SignalVu Essentials starts at $3,490 for the DPO7000 Series models and $4,990 for the DPO/DSA700000 Series models. Additional capabilities for pulse measurements and modulation analysis are available as options.
