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.
STEREO R/L
Inputs for analog stereo modulation signals. External modulation sources or the internal
LF generator can be used (stereo modulation is available with option R&S SMB-B5).
See also chapter 5.4.6, "Stereo Modulation", on page 180.
S/P DIF
Input for digital stereo signals (stereo modulation is available with option R&S SMB-B5).
See also chapter 5.4.6, "Stereo Modulation", on page 180.
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 for sweeps and list mode.
See also chapter 5.3.7.4, "List Mode", on page 159 and chapter 5.3.7.1, "Overview",
on page 147.
PULSE VIDEO
Output of internal pulse generator signal or external pulse signal fed in via the PULSE
EXT connector (video signal).
See alsochapter 5.4.5, "Pulse Modulation (PM)", on page 178 .
PULSE EXT
Input of external pulse signal or input of external trigger/gate signal for internal pulse
generator.
See alsochapter 5.4.5, "Pulse Modulation (PM)", on page 178 .
REF OUT
Output of internal reference signal.
See also chapter 5.3.4, "Reference Oscillator", on page 119.
REF IN
Input for external reference signal.
See also chapter 5.3.4, "Reference Oscillator", on page 119.
