Many coaxial connector types are available in the RF and microwave industry, each designed for a specific purpose and application. The following is a brief review (By Keysight) of common connectors used in test and measurement applications.
The spectrum analyzer, like an oscilloscope, is a basic tool used for observing signals. Where the oscilloscope provides a window into the time domain, the spectrum analyzer provides a window into the frequency domain. To get better spectrum analyzer measurements the input signal must be undistorted, the spectrum analyzer settings must be wisely set for application-specific measurements, and the measurement procedure optimized to take best advantage of the specifications. More details on these steps will be addressed in Keysight hints guide. Hint 1. Selecting the Best Resolution Bandwidth (RBW) Hint 2. Improving Measurement Accuracy Hint 3. Optimize Sensitivity When Measuring Low-level Signals Hint 4. Optimize Dynamic Range When Measuring Distortion Hint 5. Identifying Internal Distortion Products Hint 6. Optimize Measurement Speed When Measuring Transients Hint 7. Selecting the Best Display Detection Mode Hint 8. Measuring Burst Signals: Time Gated Spectrum Analysis
Signal sources provide precise, highly stable test signals for a variety of component and system test applications. Signal generators add precision modulation capabilities, and are used to simulate system signals for receiver performance testing. This guide, By Keysight, helps you improve the accuracy of your measurements that involve using RF signal sources. You may increase the accuracy of your data by using more than one of the hints in your test setup.
