Using the Keysight Vector Modulation Analysis Measurement Application to Analyze Complex Signals

Application Notes

To address your dynamic measurement needs, Keysight offers dedicated signal analysis applications for 5G NR, LTE-Advanced Pro (including NB-IoT/eMTC), WLAN 802.11ax along with general-purpose measurement applications for analysis of both standards-based signals and customized propriety signals.

 

The N9054EM0E Vector Modulation Analysis (VMA) is a general-purpose measurement application.

 

With the latest release of VMA application version 22.08 or above, a new feature is introduced to allow customers configure the signal with two segments (for example, header and data) for analyzing complex signals like DVB-S2/S2X. In some transmission systems, the frame structure consists of sections for synchronization or carrying signaling; and a section for payload data (header and data sections). Usually, different modulation schemes are necessary for these two sections because a robust reception is a requirement for the header section, while high throughput is essential for the data section.
