Is MXA N9020A a VSA or a swept-tuned spectrum analyzer?
How to tell the difference between these two types?
Thanks for your question. Since the introduction of the PSA Spectrum Analyzer in November of 2000, our analyzers with all-digital IFs are both vector signal analyzers and swept-tuned spectrum analyzers. For the X-Series we changed the name from spectrum analyzer to signal analyzer to represent the dual functionality of our analyzers. So, the MXA N9020A is both a VSA and swept-tuned analyzer. The MXA N9020A has now been discontinued, but you can learn more about the current version, the MXA N9020B Signal Analyzer, or any of the currently available Spectrum Analyzers on the Keysight website.
There are advantages to both swept-tuned analysis and to vector analysis. Swept analysis allows more flexibility between the RBW and sweep time chosen. Also, there are advantages in image protection. Vector analysis allows for amplitude and phase measurements over wider bandwidths which is needed for digital demodulation of wideband signals.
Real time analysis is a progression of vector analysis that allows for gap free analysis and newer amplitude density traces and other newer features such as frequency mask trigger and time qualified triggering.
Thank you for your detailed reply.
