ME7868A Distributed 2-Port VNA Application Flyer ME7868A Outdoor Antenna Range Solution Introduction The ShockLine ™ 2-Port ME7868A Network Analyzer Solution Antenna testing on outdoor test ranges presents a challenge for traditional VNAs. The distances involved in routing the signals between the antennas on the range and the VNA can typically preclude using coax cables because of significant insertion loss and phase instability. Additional hardware and complex methodologies are used to solve the long distance interconnect issues, raising costs and time required to make antenna S-parameter measurements on outdoor ranges. The Anritsu ShockLine ME7868A is a unique chassis-less, 2-port VNA with portable port modules covering a frequency range to 43.5 GHz. Tested with port modules spaced at 100 meters apart, the ME7868A's groundbreaking architecture allows physical placement of the VNA ports on outdoor ranges close to test antennas without the need for additional complex test hardware. 11410-02869, Rev.
