The 85514A 4-in-1 mechanical calibration module combines an open, short, load, and through in a compact unit. The product is small, easy to handle, and light weight. The through allows users to easily calibrate non-insertable devices, such as a cable or filter with male-male connectors. During the "thru" part of the calibration, the 85514A through can be used.
