Web2 days ago · [FOR RADIO EQUIPMENT] Used to measure the matching characteristics of passive and active radio equipment, such as antennas, cables, filters, attenuators, amplifiers, etc. [WIDE FREQUENCY RANGE] 23MHz to 6200MHz wide operating frequency range, full frequency range 0.25 dB and 1.5°, to achieve high accuracy measurement. WebSubject: Measurement of cable loss between LNA and antenna. The tests of the performance of the EDGE-2 electronics on the bench using an artificial antenna described in memo 126 used a lossy cable between the hot filament source and the EDGES reference plane at the input of the LNA module. This test allows a more realistic simulation of
