The Hewlett Packard HP 8514A S-Parameter Test Set measures all four S-parameters of a two-port device with a single connection, operating from 500 MHz to 18 GHz. This test set characterizes amplitude and phase response of RF and microwave devices without requiring physical reversal, making it ideal for nonreversible networks and devices requiring in-situ adjustment with full error correction.
