Content is AI-generated. Verify critical details with manufacturer-provided resources.
The Keysight N5225A operates from 10 MHz to 50 GHz, providing extended frequency coverage for millimeter-wave device testing. This broad frequency range supports applications in satellite communications, automotive radar, 5G millimeter-wave systems, and advanced aerospace testing where characterization beyond 43.5 GHz is required.
The N5225A with Option 200 is a 2-port base model with a standard test set. This configuration provides two test ports without additional front-panel jumpers, extended power range features, or bias-tees, making it suitable for straightforward 2-port S-parameter measurements of passive and active components with standard power levels.
The N5225A features ruggedized 2.4 mm male connectors on the test ports. These precision connectors support the full 50 GHz frequency range and provide excellent repeatability and durability for production testing and laboratory applications requiring measurements at millimeter-wave frequencies.
The N5225A with Option 200 achieves a system dynamic range of 127 dB from 1 GHz to 26.5 GHz, 123 dB from 26.5 GHz to 35 GHz, and 118 dB from 35 GHz to 43.5 GHz at 10 Hz IF bandwidth. From 43.5 GHz to 47 GHz, the dynamic range is 115 dB, and from 47 GHz to 50 GHz it is 107 dB, enabling accurate characterization of devices with significant insertion loss across the entire frequency range.
The N5225A with Option 200 provides maximum leveled power of 13 dBm from 50 MHz to 26.5 GHz, 10 dBm from 35 GHz to 43.5 GHz, and reduced levels of 6 dBm from 43.5 to 47 GHz and -2 dBm from 47 to 50 GHz (specification). Typical values are higher, with 18 to 20 dBm in mid-frequency ranges, providing adequate power for most device characterization applications.
Yes, the N5225A supports time domain analysis through application software S93010A for basic time domain functionality. For enhanced capabilities including time domain reflectometry, option S93011A provides all features of S93010A plus TDR, enabling detailed analysis of transmission lines, cables, and impedance discontinuities with high resolution.
Yes, the N5225A can characterize mixers and frequency converters with application software options. S93082A provides scalar mixer/converter measurement capabilities, while S93083A offers both vector and scalar mixer/converter measurements including phase and delay characterization. Option S93080A enables frequency-offset measurements for independently controlling source and receiver frequencies.
The N5225A supports both mechanical and electronic calibration methods. Mechanical calibration can be performed using standards such as the 85056A calibration kit for 2.4 mm connectors. Electronic calibration with modules like the N4693A provides faster calibration with improved repeatability. The analyzer specifications include detailed uncertainty data for both calibration methods, and calibration certification options include ISO 17025, commercial UK6, and ANSI Z540 compliance.
