Key Facts
Picture R&S®IN500 Bias Unit

20 MHz to 3000 MHz

The Bias Unit R&S®IN 500 is used to supply power to an active receiving antenna. The supply voltage is fed to the antenna via the inner conductor of the coaxial cable.

A regulated power supply unit generates the interference-free, smoothed DC voltage. The DC voltage is applied to the inner conductor of the antenna connector via a bias unit. The conductor of the receiver connector is DC-free.

The AC supply voltage of the R&S®IN500 is factory-set to 230 V AC. The unit can also be switched to 110 V AC or battery supply.

Recommended for use with the Active Receiving Antenna R&S®HE500.
