The Agilent/Keysight 35677A is a 50-ohm S-parameter test set that extends the measurement capabilities of the 3577A Network Analyzer to characterize one- and two-port devices from 100 kHz to 200 MHz. It delivers full four-parameter S-parameter measurements (S11, S21, S12, S22) with directivity exceeding 40 dB, enabling precise reflection and transmission analysis in both forward and reverse directions.
