The Keysight N5234A is a 43.5 GHz PNA-L Microwave Network Analyzer engineered for high-accuracy S-parameter measurements across R&D and manufacturing environments. This 2-port benchtop instrument delivers dynamic range to 127 dB with trace noise as low as 0.003 dB rms, making it well-suited for passive component characterization and active device measurement including amplifiers and frequency converters.
– Technical Specifications

• USB, LAN, and GPIB connectivity
• Benchtop form factor: 24 × 20 × 16 inches, 50 lbs
– Typical Applications
Passive component validation, active device characterization, millimeter-wave analysis, signal integrity assessment, and materials measurement.
– Compatibility & Integration
The N5234A shares firmware with the PNA series and maintains 100% compatibility with the N5230C, requiring no changes to existing test setups or measurement code. The N5234A entered obsolescence as of June 1, 2024, with reduced standard support; Keysight offers hardware and firmware upgrades to the N5234B model for continued technical support and serviceability.
