Improved EMC measurements from antenna and pre-amplifier pairs
The company’s Double-Ridged Waveguide Horn and BiConiLog antennas are now available together with the matched pre-amplifiers. Models 3116C-PA and 3117-PA antenna and pre-amplifier combination are calibrated as a single unit. This allows for mismatches between the antenna and the pre-amplifier to be taken into account in the antenna factor (AF) which is provided with each unit.
Key characteristics of each antenna include single lobe radiation, extremely low AF, and flexible mounting. Model 3116C-PA is suitable as a receive antenna for emissions testing from 18 GHz to 40 GHz. Model 3117-PA is used as a receive antenna for emissions testing from 1 GHz to 18 GHz.
The hybrid BiConiLog antenna, Model 3142E-PA, combines performance and compact size with a pre-amplifier module. Designed for emissions testing, the 3142E-PA enables users to measure a frequency range of 30 MHz to 6 GHz in one sweep, eliminating the need for multiple antennas and time-consuming equipment set up. The antenna and pre-amplifier module are calibrated together, including the cable section that connects the module to the antenna port. Flexible mounting is also offered with this antenna as with all the horn antennas noted above, the mounting bracket accepts popular mounting arrangements.
