Description of the Connectors
AC SUPPLY AND POWER SWITCH

When the R&S SMC is connected to the AC supply, it automatically sets itself to the correct range for the applied voltage (range: see type label). There is no need to set the voltage manually or change fuses.

The power switch can be set to two positions:
  • 0
    The instrument is disconnected from the mains.
  • I
    The instrument is power-supplied. It is either ready for operation (STANDBY) or in operating mode, depending on the position of the ON/STANDBY switch on the instrument front.

See also data sheet and "Connecting the Instrument to the AC Supply".

FUSES

The R&S SMC is fully fused by two fuses IEC60127-T3.15H/250 V.

The fuses are accommodated in the fuse holders next to the power connector. Use only fuses of the mentioned type.

CAUTION! Danger of shock hazard!. Before replacing the fuses, disconnect the power cord from the R&S SMC.

IEC 625/IEEE 488

IEC-bus (IEEE 488) interface for remote control of the instrument.

See also "GPIB Bus Interface" and "GPIB Interface (IEC/IEEE Bus Interface)".

Note: In order to avoid electromagnetic interference (EMI) caused by open lines, always terminate any connected IEC-bus cable with an instrument or a controller.

PULSE VIDEO

Output of internal pulse generator signal or external pulse signal fed in via the PULSE EXT connector (video signal).

See also"Pulse Modulation (PM)" .

PULSE EXT / INST TRIG
  • PULSE EXT
    Input of external pulse signal or input of external trigger/gate signal for internal pulse generator.
    See also "Pulse Modulation (PM)".
  • INST TRIG
    Input for external trigger for sweeps.
    See also "Overview".
REF OUT

Output of internal reference signal.

See also "Reference Oscillator".

REF IN

Input for external reference signal.

See also "Reference Oscillator".

LAN CONNECTOR
Ethernet interface
  • For integrating signal generators in a network
  • Remote control of signal generator
  • Remote access to the signal generator
  • Firmware update
OCXO

Oven-controlled reference oscillator (option R&S SMC-B1)

The OCXO generates a very precise 10 MHz reference signal. It needs some minutes of warm-up time to reach its nominal frequency.

Refer also to the data sheet for detailed information.

USB CONNECTORS TYPE A

USB (universal serial bus) interfaces of type A (host USB).

  • Connection of peripherals such as mouse, keyboard, etc.
  • Connection of memory stick for file transmission
  • Firmware update

See also "Connecting USB Devices".

USB IN

USB (universal serial bus) interface of type B (device USB).

This interface can be used for remote control of the instrument.
