Noise Source, 10 MHz to 18 GHz, nominal ENR 6 dB
346A
Noise Source
The Keysight 346A noise source is the ideal companion to Keysight's noise figure solutions. Since it is broadband (10 MHz to 18 GHz), it eliminates the necessity for several sources at different frequency bands. The low SWR of the noise source reduces a major source of measurement uncertainty; reflections of test signals. The very small change in reflection coefficient (<0.01) from ON to OFF is designed especially for accurate characterization of input-impedance-sensitive devices (like GaAsFETs and many UHF amplifiers).

Bridges
-
Equip your testing environment with portable, precise Wheatstone bridges and Kelvin double bridges from Transcat. The Wheatstone bridge is a device containing a divided bridge circuit for taking highly accurate resistance measurements. It captures the value of an unknown resistance, in comparison to known resistors within the circuit. Precision bridges provide exact resistance measurements in the miliohms (m_) to megohms (Mohm) range within their specified accuracies. We offer portable Kelvin double bridges, which are forms of the Wheatstone, designed to measure low resistance – with high accuracy. Transcat also stocks individual resistors, which provide resistance standards in low to high values. They operate in conjunction with potentiometers or bridges.
