Features: 7 Inch Touchable Screen: This VNA adopts full touching screen design, 7.1inch large size allows you to see the data more clearly. With 4 physical buttons, you can quickly set parameters such as frequency, giving you a better experience. Preferred Material: The use of all-metal casing can effectively shield electromagnetic interference and ensure measurement accuracy. With the screenshot function, it can save the screen images to the internal memory card at any time. The built-in memory card has a capacity of 8GB, which can easily store the screenshot images of the calibration status. Support TDR function, can be used to measure cable length. Portable Size: Small and portable, and designed with a back stand for desktop use. The fuselage adopts N-type RF connector and is equipped with an N-to-SMA adapter, which is convenient for connecting various DUTs. With a measurement speed of 400 points/second, it can realize quasi-real-time measurement, and the maximum number of scanning points can be set to 1001 points. With storage bag: Comes with a storage bag to allow you to neatly store the vector network analyzer and accessories in the bag, which is easy to carry and not easy to lose.
