Keysight Technologies Inc. N7621B-FFP Noise Power Ratio (NPR), fixed perpetual license

Signal creation

• Create an NPR with a user-defined notch width with excellent feed through suppression
• Excellent performance: dynamic range of > 60 dBc and 0.5 dB flatness
• Supports more than 100,000 tones over more than 2 GHz of bandwidth and a carrier frequency range from DC to 44 GHz
• The synthetic noise parameters and signal statistics are well defined and accurately reproducible

Use case

• Easily define noise bandwidth and phase distribution with confidence and repeatability
• Choose from a wide range of hardware for various price and performance needs
• Accurate and repeatable characterization of a DUT in a predictable and relatively short time period
• Automated programming environment allows software to be quickly implemented in new or existing test systems

Licensing

• Fixed, perpetual license
• Also available as a transportable license (Option FTP) or fixed, 1 month license (Option FFP)

Option FFP is designed for a large number of tones to simulate Gaussian Noise with a notch in it. The individual tone properties are not directly accessible by the user. The NPR application provides methods to define the noise signal including the noise bandwidth (number of tones and the tone spacing), the phase type (random, parabolic, and constant) and the notch width and offset from the noise center. The NPR interface also allows the user to specify the IMD correction level desired within the notch (in-band corrections).

This option can be added as a product upgrade.
