Noise Source Control (NOISE SOURCE)
Using the NOISE SOURCE connector, an external noise source can be switched on/off, in order, e.g., to
measure the noise figure of units under test (UUTs). Usual noise sources require a +28 V signal to be
turned on. At 0 V, they are turned off. These supply voltages are delivered by the connector. Maximum
current is 100 mA..
External Trigger Input (EXT TRIG/GATE)
The EXT TRIG/GATE connector is used for controlling the measurement via an external signal. The
trigger voltages are TTL level (Low < 0.7 V, High > 1.4 V), typ. input impedance is 10 kOhm.
Mouse Connector (MOUSE)
A PS/2 connector is provided at the rear panel to connect a PS/2 mouse:
