The real-time clock of the N8973A noise figure analyzer time-stamps data files, making it easier for users to carry out a post-analysis of the results obtained from an experiment. Its comprehensive, built-in help menu enables users to make quick reference whenever they need it. This eliminates the need for printed manuals. Users can view the measurement results on a larger display by connecting the noise figure analyzer to a VGA monitor via its VGA output port, a very useful feature for when a detailed representation of the results is required.

Can be Used in an Automated System

The GPIB and RS-232 ports on the rear panel of the noise figure analyzer are used for integrating the test solution into an automated system. These ports are used when the operators are required to remotely control the tester. Its LO GPIB port provides a means of driving a local oscillator in a measurement set up that utilizes this feature. The N8973A noise figure analyzer is designed for applications in the < 3 GHz frequency coverage. The capability of displaying gain and noise figure in real-time makes it an ideal choice for measurements involving amplifiers and frequency converting devices, allowing users to apply loss corrections using its loss compensation modes. Its frequency modes allow for easy to carry out measurements at pre-determined frequencies. The technician can quickly set a specific frequency depending on the needs of any testing exercise.
