原廠英文說明
The N8973B,N8974B,N8975B,N8976B high performance noise figure analyzer is designed to make fast, accurate and repeatable noise figure measurements.When paired with an SNS Series noise source and U7227 Series USB preamplifier the ENR data from the SNS and USB preamplifier data automatically downloads into the N8973B,N8974B,N8975B,N8976B. The N8973B,N8974B,N8975B,N8976B has a multi-touch interface that allows stretch, pinch, and drag gestures. Most menus can be accessed with the tap of a finger without changing screens.Noise source calibrations for Y-Factor measurements have been streamlined by allowing combined calibrations for up to 12 DUT setups in a single step. Saving valuable test time can be achieved for many types of DUT’s by using the internal calibration feature, which does not require a user calibration to be performed.A built-in noise figure uncertainty calculator can prepopulate data from the SNS noise source, USB preamplifier, as well as all the required instrument parameters such as analyzer noise figure, gain and noise figure uncertainty, and match.Default noise figure settings offer simultaneous noise figure and gain measurements.By using Table view several measurements including Noise Figure, Noise Factor, Y-Factor, Gain, Phot, Pcold, and Teffective can be viewed simultaneously in tabular form.
