The E5071B network analyzer offers fast and accurate measurements for RF components. Its wide dynamic range and low trace noise enables much higher test quality and throughput than comparable network analyzers. The E5071Bs advanced usability such as 10.4 inch LCD, touch screen, built-in Microsoft Visual Basic for Application (VBA), and 2 and 4-port electronic calibration (ECal) increases your productivity. The LAN connectivity, in addition to GPIB, offers an easy connection to your PC environment. Built-in 2, 3, and 4 test ports provide simultaneous measurement of all signal paths for components with up to four ports. This advanced architecture minimizes the number of sweeps to complete a multiport measurement and further improves test throughput. The combination of the 4-port E5071B and the E5091A multiport test set offers a test solution for up to 9 ports (or up to 14 ports with two E5091A test sets), and is tailored for testing multiport wireless components such as handset front end modules.
