Description

The VNA4435 vector network analyzer covers 100 kHz to 43.5 GHz for C/X/Ku/K/Ka-band microwave product testing in microwave communication, satellite communication and aerospace/defense R&D and production.

Complete analysis and calibration algorithms include port matching and AFR fixture simulation, time-domain analysis and eye-diagram test. External frequency-extension modules reach 40–110 GHz and beyond, and the instrument adapts to most mechanical and electronic calibration kits with customized test software available. The VNA4435 also offers a factory hardware upgrade path to 67 GHz (VNA-P class), protecting your investment for 224G applications.

Key features

  • Frequency range 100 kHz to 43.5 GHz; 2 or 4 ports
  • Excellent dynamic range: 125 dB (typ.) @ 43.5 GHz
  • Ultra-low trace noise; high power accuracy ±0.5 dB
  • TDR and enhanced TDR (eye diagram, rise time, skew)
  • AFR automatic fixture removal solves non-standard connector testing
  • External extension modules for 40–110 GHz+ mmWave test
  • Factory upgrade path 43.5 GHz → 67 GHz for 112G→224G evolution
