Product Introduction:
Agilent 346A noise source is the ideal collaborative tool for noise factor solutions. Because it is a broadband noise source (10 MHz to 18 GHz), there is no need to use multiple sources in different frequency bands. A low SWR of the noise source can reduce the main source of measurement uncertainty, which is the reflection of the test signal. The change in reflection coefficient from "on" to "off" is very small (less than 0.01) and is designed for accurate characterization of input impedance sensitive devices (such as GaAsFET and many UHF amplifiers).
Features:
-
Frequency range: 10 MHz to 18 GHz
-
Voltage standing wave ratio: < 1.3:1
-
Connector: BNC (negative head) Input offset / 3.5mm (positive head)
-
Low SWR can reduce the uncertainty of noise coefficient measurement
-
Individually calibrated ENR values at specific frequencies
-
Calibration procedures are provided on a floppy disk and can be easily loaded into the NFA series of noise factor analyzers
