The Keysight (Agilent) 11729C Carrier Noise Test Set is a core component in phase noise measurement systems, enabling precise characterization of signal stability. It supports both Phase Detector and Frequency Discriminator methods, using an internal or external reference to up-convert, and down-convert signals from 1.28 to 18 GHz into a 5–1280 MHz IF range. The system ensures consistent IF output levels of +7 dBm or more.
With a downconverter input power range from +7 to +18 dBm and operation over 8 frequency bands, the 11729C delivers reliable performance across a wide dynamic range for demanding RF and microwave analysis.
Testwall can supply the used Keysight (Agilent) 11729C, fully tested. With expert support and global delivery, Testwall ensures high-performance instrumentation with unmatched reliability and service quality.
