Calibration Standard
Fixed Load
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.
