Agilent/Keysight 8719A

The Agilent/Keysight 8719A is a microwave network analyzer covering 130 MHz to 13.5 GHz, designed for RF and microwave component characterization. It integrates a fast-sweeping synthesized source with a mechanical switching S-parameter test set, delivering 85 dB dynamic range (99 dB with Option 003) and measurement speeds suited to production and R&D environments.

Technical Specifications

• Frequency range: 130 MHz to 13.5 GHz


• Frequency resolution: 100 kHz standard; 1 Hz with Option 001


• Power range: −10 dBm to −65 dBm


• Power level: −10 dBm ± 3 dB


• Dynamic range: 85 dB (99 dB with Option 003)


• Harmonics: 3 million cycles (typical)


• External reference input: 1, 2, 5, 10 MHz (±200 Hz at 10 MHz), −10 to +20 dBm, 50 ohms

Key Features

• Integrated switching test set eliminates external components for basic S-parameter measurements
