Matlab software expands Keysight oscilloscope features
Keysight Technologies has announced that it included a frequency domain analysis (FDA) option for some of its oscilloscopes. According to the company, the option allows users to extend the analysis capabilities of the oscilloscopes in the frequency domain. The software comes with a range of Matlab tools to further enhance the analysis capabilities of these instruments, added Keysight.
The FDA option can be used with Keysight's Infiniium and InfiniiVision series oscilloscopes and enables them to acquire live signals from the oscilloscope and visualise them in the frequency domain as well as make key frequency domain measurements. The option is provided with its source code to enable users to write their own extensions. In addition, Keysight provides a number of Matlab software tools.
The application provides capabilities to address several frequency domain analysis challenges, including power spectral density (PSD) and spectrogram visualisation, commonly found in spectrum analyser and frequency domain analysis software; and frequency domain measurements in an application including relevant peaks in the PSD and measurements such as occupied bandwidth, SNR, total harmonic distortion (THD), spurious free dynamic range (SFDR) and frequency error.
The oscilloscope configuration through the application allows for repeatable instrument configuration and measurements, and optionally includes additional SCPI commands for more advanced instrument setup. The insertion of additional custom signal processing commands prior to frequency domain visualisation, as needed, offers more advanced analysis insight. In addition, it also provides live or post-acquisition analysis of time-domain data in Matlab software.
