11729B Agilent Communication Analyzer
- Frequency range: 5 MHz to 18 GHz
- IF output bandwidth: 5 to 1280 MHz
- Phase noise and AM noise measurements
- Low system noise floor
The Agilent HP 11729B, combined with an Agilent HP 8662A synthesized signal generator and a baseband spectrum analyzer, form a complete broadband measurement system for phase noise and AM noise testing of microwave oscillators, 5 MHz to 18 GHz. With one versatile measurement system, direct AM noise measurements and two methods of phase noise measurements can be made, at offsets from the carrier of < 1 Hz to 10 MHz. These three operating modes allow a wide variety of sources, from low noise stabilized sources to free-running sources with high drift to be measured.
The Agilent HP 11729B/8662A combination includes the critical low noise microwave reference signal (which determines the system noise floor). The wide frequency range and low system noise floor of the Agilent HP 11729B/8662A enable a signal system to be used on a broad range of sources. Typical system noise for a 10 GHz source is less then -123 dBc/Hz at a 10 kHz offset, allowing characterization of most high-performance sources.
