Bird Variable RF Signal Sampler

Bird Models 4273 (1.5 to 35 MHz, 5 kW max.) and Model 4275 (20 to 1000 MHz, 2 kW max.) are "stand alone", wide-range, THRULINE® RF coupling probes for spectrum analysis, RF signal observation on a scope, or frequency counting and control. They feature very low VSWR throughout a broad frequency and attenuation range. Insertion loss is a negligible 01. dB. Both Models produce and unrectified sample at the BNC port that is adjustable. Once adjusted, the setting can be locked in place. The main power line connectors are Bird QC type.   4273 Specifications 4275 Specifications Impedance: 50 ohms nominal Coupling: Adjustable as shown within ±3dB Ambient Temperature Range: -40°C to +45°C Connectors: QC type as specified Nominal Size: 2 51/64" L x 2 7/8" W x 1 1/4" D Weight: 10 oz.
