SIGNAL VALID
Output of valid signal. This signal marks the valid signal times (valid level and frequency
indication). The signal is generated automatically.
INSTR TRIG
Input for external trigger of sweeps and list mode.
See also chapter 5.4.15, "List Mode", on page 227 and chapter 5.4.14.1, "Over-
view", on page 208.
PULSE VIDEO
Output of internal pulse generator signal or external pulse signal fed in via the PULSE
EXT connector (video signal).
See alsochapter 5.4.12.5, "Pulse Modulation (PM)", on page 199 .
PULSE EXT
Input of external pulse signal or input of external trigger/gate signal for internal pulse
generator.
See alsochapter 5.4.12.5, "Pulse Modulation (PM)", on page 199 .
REF OUT
Output of internal reference signal.
See also chapter 5.4.4, "Reference Oscillator", on page 159.
REF IN
Input for external reference signal.
See also chapter 5.4.4, "Reference Oscillator", on page 159.
OCXO
Oven-controlled reference oscillator (option R&S SMBV-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.
AC SUPPLY AND POWER SWITCH
When the R&S SMBV 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 instrument comes with or without a power switch, depending on the design of the
otherwise technically equivalent power supply unit.
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 instru-
ment front.
