Tektronix, Inc. introduces a Signal Source Analysis Suite for the WCA200A, RSA3300A and RSA3408A real-time spectrum analyzers. The software package provides engineers with automated signal source analysis tools to characterize phase noise, jitter, frequency deviation and settling time for transient RF signals. The suite also provides exclusive time-related measurements such as phase noise over time, a tool for engineers looking for elusive intermittent effects. The analyzers enable characterization of these circuits and components and are particularly useful for looking at transient responses such as frequency settling or intermittent signals causing interference or spurs. Through automated set-ups and key measurements such as phase noise measured over time, frequency settling time analysis and spurious signal search, the Signal Source Analysis Suite for real-time spectrum analyzers offers the engineer all the advanced analysis and troubleshooting capabilities needed to address these design challenges.
