The HP/Agilent 35676A Reflection/Transmission Test Kit is a precision accessory that expands the measurement capabilities of the HP 3577A Network Analyzer. It enables accurate reflection and transmission measurements along with impedance characterization in 50 Ohm systems across a broad frequency range. The kit integrates a precision resistive divider, 50 Ohm reference load, coaxial short, and calibration standards to support S-parameter acquisition and component characterization for filters, amplifiers, and RF/microwave devices.
