The 351B2 is a male BNC 50Ω precision fixed termination designed for VNA calibration, with a DC to 2.0 GHz VSWR of 1.04, 2.0 to 4.0 GHz VSWR of 1.10, and 4.0 to 10.0 GHz VSWR of 1.20. It supports 2 watt CW and 1 kW peak power handling. The part features a BNC connector and is intended for high-accuracy measurement systems requiring low VSWR.
A precision fixed termination (or load) consists of an immovable, (fixed) termination which, when mated to the end of a trans-mission line or cable, absorbs nearly all of the signal energy traveling toward it. An ideal “matched” condition exists when a termination with an impedance value of Z0, is connected to the end of a transmission line or cable that also has a characteristic impedance of Z0. Such an ideal “matched” condition (one with no mismatch between the termination and its mated line or cable) is critical if a voltage standing wave ratio (VSWR) of 1.0:1 is to be achieved in a system with a 50 or 75 ohm impedance value. Simply put, the more closely the 1.0:1 ratio is approached, the more accurate the measurements that can be made from a system.
