LNF-PS8 is a compact 8-channel power supply designed for LNF’s Low Noise Amplifiers. The drain voltage is regulated and adjustable within a wide range, and the gate voltage is automatically and continuously adjusted to give a set drain current. Vd, Vg and Id are displayed on the LCD monitor screen for easy bias control. Vd and Id are set by trim potentiometers on the front panel. The LNF-PS8 is redesigned from ground up and features new low noise electronic components for much improved performance compared to previous models. There’s also a drain voltage sense function for situations where bias wire resistance is significant. The display can be switched off for ultra-low noise operation. The power supply is powered by LNF’s Power Block, either LNF-PBA or LNF-PBA-HP.
