The new CX-4 is an ultra low noise FET preamplifier, operating in room temperature down to deep cryogenic environments (T = 4.2 K, liquid helium). It is an improved version of its predecessor NexGen3 KC05.
The setup is easy: simply connect the signal and bias voltages to the controller and you are ready to go. The CX-4 is designed for fully-automated plug-and-play functionality.
Key Features
- ultra low input noise (typ. 0.31 nV/√Hz @ 1 MHz)
- frequency range 1 kHz to 4 MHz
- input impedance > 15 MΩ
- small size and tiny thermal load of only 300 μW per channel
- fully-automated plug-and-play room temperature controller included!
