Resolving with the MSA500 series signal analyzer! Introducing application examples.
Let me introduce RBW (Resolution Bandwidth). Even with the same input signal, the peak frequency and power values can differ depending on the RBW settings, so it is necessary to consider the appropriate RBW settings based on the signal being measured and the test content. To address this issue, we have the MSA500 series signal analyzer. Once the maximum signal level is searched, it is possible to perform detailed analysis of the signal in real-time mode. 【Case Study】 ■Challenges - Changing the RBW bandwidth can lead to different measurement results even for signals with the same maximum power. - If there are two or more frequency components within the RBW bandwidth, the power values will be summed and integrated, resulting in different displayed outcomes. ■Solution - By pressing the "AUTO TUNE" key in sweep mode, the analyzer automatically searches for the maximum level signal within the measurable frequency range with optimal settings. - Detailed analysis of the signal can be performed in real-time mode. *For more details, please refer to the PDF document or feel free to contact us.
