TA050 attenuators must be used with a matched 50 source and load. If users wish to attenuate a signal before feeding it into a high-impedance measuring instrument, they must add a 50 feedthrough terminator such as Pico TA051 ( < 898-6791') 898-6791/ ). Pico Attenuator Set TA050 BNC 50 1W 1GHz, 3, 6, 10, 20 dB. The Pico TA050 attenuator set consists of 4 coaxial attenuators designed for use with signals up to 1GHz. Each attenuator has a male and a female BNC connector.. Bandwidth DC to 1GHz Attenuation 3, 6, 10, 20 dB Maximum power dissipation 1W Input impedance 50 Output impedance 50 VSWR 1.5:1 or better Dimensions 56 x 20 x 17 mm Connectors BNC, 1 male + 1 female Shielded inner box with plastic shell Weight 24g each
