IF / Video Out

The female BNC connector is used as an intermediate frequency (IF) output of approximately 20 MHz or as video output at the set video and resolution bandwidth. The setup menu (SETUP key) is used to select between the IF and video output.

Note: This connector cannot be used simultaneously with the AF output connector on the front panel.

Noise Source Control

The noise source control female connector is used to provide the supply voltage for an external noise source, e.g., to measure the noise figure and gain of amplifiers and frequency converting DUTs.

Conventional noise sources require a voltage of +28 V in order to be switched on and 0 V to be switched off. The output supports a maximum load of 100 mA.

An LED indicates the status: green for +28 V, red for overload and off for 0 V.

AUX Port

The 9 pole SUB–D male connector provides control signals for controlling external devices. The voltage levels are of the TTL type (max. 5 V).
