Agilent/Keysight 8753C

The Agilent/Keysight 8753C is a vector network analyzer for RF and microwave device characterization from 300 kHz to 3 GHz (extendable to 6 GHz with Option 006). The instrument integrates a synthesized RF source with a dual-channel, three-input receiver to measure transmission and reflection parameters, magnitude, phase, and group delay responses across linear and non-linear networks.

Technical Specifications

Frequency Range: 300 kHz to 3 GHz standard; 300 kHz to 6 GHz with Option 006 Output Power: +10 dBm nominal; source delivers > 100 mW. Option 004 (step attenuator) extends dynamic output range to −85 to +10 dBm. Dynamic Range: 100 dB with maximum input of 110 dBm. Tracks magnitude and phase with ±1.5 dB and ±10° accuracy across 300 kHz to 3 GHz; ±0.05 dB dynamic accuracy over 40 dB range. Input Power: Maximum 250 mW (+24 dBm). Source Match: 20 dB (300 kHz to 1.3 GHz), 16 dB (1.3 to 3 GHz), 14 dB (3 to 6 GHz). Test Ports: Two 50 Ω Type-N female connectors; precision 7 mm ports available.
