Stop
Input and output for stopping the sweep in all modes.
This connector is bidirectional. Used as:
●
"Input": enables you to stop a sweep triggered by an external network analyzer.
●
"Output": enables the R&S SMA100B to stop the sweep of an external network
analyzer.
Marker User1
Output signal for marker or trigger signal.
Signal Valid
Output signal that determines the valid signal times (valid level and frequency) for all
analog modulations.
Inst Trig
BNC connector for input of external trigger signals. The signals trigger sweeps and list
mode.
See Chapter 7.1, "Signal generation and triggering in the sweep and list modes",
on page 173.
EFC
BNC connector for input of an EFC (external frequency control) signal for electronic
tuning of the internal reference frequency.
See Chapter 9, "Reference oscillator", on page 294.
Ref In/Ref Out
Input/output for external reference signal.
BNC connectors for reference signals from 1 MHz to 100 MHz.
SMA connectors for 1 GHz reference signals.
How to: Chapter 3.1.10, "Connecting to Ref In/Ref Out", on page 33
Clk Syn/Clk Syn N
Connectors for output of the clock synthesizer signal, or the inverted signal.
Pulse Ext
Input for an external pulse modulation signal or an external trigger/gate signal for the
pulse generator.
Pulse Video
Output of the internal pulse generator signal or the looped through pulse signal from
Pulse Ext connector (video signal).
See Chapter 5.4.1, "Pulse modulation settings", on page 84.
Pulse Sync
Output signal for synchronizing the pulse generator signal. The synchronization signal
is generated at the beginning of each pulse. For double-pulse generation, the synchro-
nization signal is generated at the beginning of the first pulse.
