The HP / Agilent E5070B's 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 HP / Agilent E5070B provides built-in balanced measurement capability, which enables you to test balanced components such as SAW filters, differential amplifiers, and high-speed digital cables/connectors. Features 300 kHz to 3 GHz 125 dB dynamic range at test port (typical) 9.6 µs/point sweep speed 0.001 dB rms trace noise Integrated 2-, 3- and 4-ports with balanced measurements.
