Q1: How to use a vector network tester?
A1: First, ensure the instrument has been preheated and stabilized. Clean the connectors between the test port and the DUT and check that the connecting cables are intact. Next, enter the instrument's operation interface, set parameters such as the test frequency range, number of points, and power according to your test requirements, and select the appropriate test mode. Calibrate according to specifications. After calibration, correctly connect the DUT to the test port, start the test, and wait for the instrument to acquire data.
Q2: What types of vector network testers are there?
A2: Vector network testers are primarily categorized as benchtop, portable, modular, and specialized types integrated into semiconductor test systems. There are also specialized vector network testers for high-frequency bands such as millimeter-wave and terahertz, as well as variants with enhanced features such as time-domain analysis and multi-port expansion to meet the needs of different industries and applications.
Q3: What factors affect the test accuracy of a vector network tester?
A3: The test accuracy of a vector network tester is affected by a variety of factors, including the instrument's own systematic errors, calibration quality, test environment, DUT characteristics, the quality of test accessories and connectors, and the operator's professionalism. These factors combine to determine the accuracy and reliability of the final measurement results.
Tips: How Do You Calibrate a Vector Network Analyzer?
First, ensure the instrument and test environment are preheated and stable. Connect calibration components (such as open, short, load, and thru) to the test ports. Next, follow the instrument menu to select the calibration type (such as SOLT) and perform calibration for each port. The system will automatically measure and store the error model. Finally, verify the calibration results to ensure that the measurement accuracy meets the requirements. This process effectively eliminates systematic errors and ensures accurate and repeatable test data.
