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

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 (universal serial bus) interfaces of type A (host USB).
- Connection of peripherals such as mouse, keyboard, etc.
- Connection of memory stick for file transmission
