Keysight U9391F Comb Generator 10 MHz to 50 GHz Small and Lightweight NIST Referenced Phase Reference Standard
The Keysight U9391C/F/G comb generator was designed as a phase reference standard to provide precision phase calibration for non-linear measurements using the PNA-X non-linear vector network analyzer (NVNA), referenced to the National Institute of Standards and Technology (NIST). Additionally, the comb generators can be used to calibrate PNA and PNA-X network analyzers for phase and delay measurements of frequency converters without requiring reference or calibration mixers.
Comb generators generate frequency harmonics at integer multiples of an RF input signal. Generally, comb generators available in the open market today are made with SRD diodes. The U9391C/F/G comb generator is based on the Keysight InP MMIC technology to ensure superior phase stability of the combs.
- Output frequency: 10 MHz to 50 GHz
- Input frequency: 10 MHz to 6 GHz
- 1, 2, 4, 8 or 16 divide ratio
Keysight's new comb generator offers a customer selectable USB controlled frequency divider which allows for broad range of input signal frequencies from 10 MHz to 50 GHz and small minimum tone spacing of 10 MHz. The input power and fundamental frequency have lower sensitivity than other comb generators. So you can calibrate the comb generator at a single input power level and frequency and then successfully apply the calibration across a wide range of input powers and fundamental frequencies.
- Excellent amplitude and phase flatness enable it to be used as a precision calibration phase reference standard for the PNA, PNA-X, and NVNA
- NIST referenced phase calibration guarantees a reliable reference to international standards
- Embedded calibration data can be easily accessed via the plug-and-play USB interface
- The USB interface further facilitates frequency divider control and calibration data retrieval via the PNA-X
- Rugged 1.85 mm, 2.4 mm, and 3.5 mm bulk-head connectors guarantee high repeatability throughout multiple connects and disconnects
- The sine-to-square wave converter is provided as a standard accessory
- The hand grip (U9391G only) is designed for better gripping and as a heat insulator for user's handling
- Combined with the Keysight Signal Optimizer software (K3101A) for wideband calibrations of signal analyzers and oscilloscopes
