Instrument Interfaces

AF Output

A miniature telephone jack can be used at the AF OUTPUT connector to connect an

external loudspeaker, a headphone set or, e.g., a LF voltmeter. The internal resistance is

10 ohms and the output voltage can be controlled with the volume controller on the left side

to the connector. When a jack is plugged in, the internal loudspeaker is automatically

turned off.

Probe Connector (PROBE POWER)

To allow the connection of probes, the R&S ESCI provides the PROBE POWER power connectors. The

3-pole connector delivers the power supply voltages +15 V and -12,6 V and ground.

The connector is also suited for powering the high-impedance probes from Hewlett Packard.
