Mixed-signal analysis continues to depend heavily on advanced software to simplify design tasks and handle the massive amounts of data generated by test equipment. Vendors continue to deliver high-performance equipment and then build on this hardware using new software products. Sometimes these software tools are free while others are available for an additional charge.
For example, Keysight Technologies’ N9040B UXA Signal Analyzer (Fig. 1) handles signals from 3 Hz to 26.5 GHz. Its full-band real-time spectrum analyzer capabilities have a 100% probability of intercepting signals with a duration as short as 3.84 µs.
The N9040B runs Microsoft Windows that supports the measurement and analysis applications. The standard suite includes the 89600 VSA software that is a set of tools for signal demodulation and vector signal analysis. Keysight’s PowerSuite provides one-button power measurements.
Keysight has added new software including the N9068C phase noise, N9069C noise figure, and N9063C analog modulation measurement applications. These are available for an additional cost. The N9063C application has features like one-button measurements to calculate metrics such as AM depth, FM deviation, total harmonic distortion (THD), and signal-to-noise-and-distortion ratio (SINAD). The N9068C phase-noise application provides one-touch measurements for analyzing phase noise in frequency domain (log plot) and time domain (spot frequency).
