Agilent/Keysight 8753E

The Agilent/Keysight 8753E is a vector network analyzer for measuring magnitude and phase response of RF devices from 30 kHz to 3 GHz, with optional extension to 6 GHz. It delivers dynamic range up to 110 dB at 3 GHz and features an integrated synthesized source with solid-state switching test set for complete S-parameter characterization. The instrument supports simultaneous measurement and display of all four S-parameters across two independent channels, with flexible sweep modes including linear frequency, logarithmic frequency, list frequency, CW, and power sweep.

Technical Specifications

Frequency range spans 30 kHz to 3 GHz standard, extending to 6 GHz with Option 006. Dynamic range reaches 110 dB at 3 GHz and 105 dB at 6 GHz. The integrated synthesized source delivers up to 10 mW output power (100 mW with Option 011) with 1 Hz frequency resolution. Test port power adjusts over a 95 dB range. IF bandwidth options include 10 Hz for optimized dynamic range and 6 kHz for maximum speed. Dynamic accuracy is 0.05 dB with sensitivity to -100 dBm.
