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

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. The DPO7000 supports acquisitions up to 100 Mpts at 40 GS/s on four simultaneous channels.

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 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 downconverted frequency span of interest, to 20 GHz real time, may be exported for further analysis in tools such as RSAVu and MATLAB*1.

Choosing the Right Scope for the Job

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. The DPO7000 oscilloscopes provide a cost-effective single-shot bandwidth of up to 3.5 GHz with 100 Mpts.
