The HP Agilent 8753D is a vector network analyzer operating from 30 kHz to 3 GHz, purpose-built for S-parameter characterization of RF and microwave networks. It combines a synthesized RF source, integrated S-parameter test set, and dual-channel three-input receiver to measure magnitude, phase, group delay, and time-domain responses. This unit ships with Option 075 (75-ohm impedance test set with Type-N connectors) and Option UK6 (commercial calibration certificate with test data). The instrument delivers up to 110 dB dynamic range at 3 GHz and features a large color display supporting rectangular, polar, and Smith chart formats.
