Product Description:
The 346B Keysight noise source is the ideal collaborative tool for Keysight noise factor solutions. Because it is a broadband noise source (10 MHz to 18 GHz), there is no need to use multiple signal sources on different frequency bands. The low SWR of the noise source can reduce the main source of measurement uncertainty, namely the reflection of the test signal. The 346B's high ENR, low SWR and various connectors make it a versatile noise source. Added a special option H01 that supports high ENR (21 dB typical) DE and can measure high noise figure devices; Add option H42 to measure direct broadcast satellite (DBS) low noise unit inverter.
Features:
Frequency range: 10 MHz to 18 GHz
Voltage standing wave ratio: < 1.3:1
Connector: BNC (negative) Input bias / 3.5mm (positive)
Low SWR reduces the uncertainty of noise factor measurement
Individually calibrated ENR values at specific frequencies
Calibration programs are available on a floppy disk and can be easily loaded into the NFA series of noise factor analyzers
3 year standard warranty
