Automatic Test System for Frequency Response Characteristics of SAW Device

Abstract:

To solve complex measurement and difficult remote operation in the test for frequency response characteristic of SAW device, an automatic test system for frequency response characteristic of SAW device based on vector network analyzer is proposed. The system consists of the vector network analyzer, the crossover cable, the computer, the fixtures and the SAW device. The user interface of test system is developed with the VB language. By means of calling the VISA-COM library, the SCPI commands can send to the vector network analyzer. Many functions of the automatic test system for frequency response characteristic of SAW device include the settings of measurement parameters, the measurement calibration, the data storage, the data display, the data transmission, the marker analysis and the data output. By the actual measurement of a SAW device with the center frequency at 101.764MHz, the experimental results show that the transmission loss of SAW device is-27.532dB, and the reflection loss is-7.715 dB.
