Bird Electronics 4273 Overview

The Model 4273 is a "stand alone" wide-range THRULINE® RF coupling probe for spectrum analysis, RF signal observation on a scope, or frequency counting and control. It features a very low VSWR over a broad frequency and attenuation range. Insertion loss is a negligible 0.1 dB. The 4275 produces an unrectified, non-directional sample at the BNC port that is adjustable. Once adjusted, the setting can be locked in place. The main power connectors are Bird® QC type.
