For detailed information on the sweep modes and the triggering, see Chapter 6.1, "Sig-
nal Generation and Triggering in the Sweep and List Modes", on page 156.
EFC
Input connector for an EFC (external frequency control) signal for electronic tuning of
the internal reference frequency.
See Chapter 8, "Reference Oscillator", on page 268.
Ref In/Ref Out
Input/output for external reference signal.
Incl. dedicated connectors for the 1GHz reference signal.
See Chapter 8, "Reference Oscillator", on page 268.
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 4.4.1, "Pulse Modulation", on page 76.
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.
LF
Output for internal LF generator signal.
See also data sheet and user manual, section "Analog Modulation".
Ext 1/2
Inputs for external analog modulation signal, and an external detector voltage.
See Chapter 4, "Analog Modulations", on page 73.
AC supply and power switch
The AC power supply connector and the main power switch are located in a unit on the
rear panel of the instrument.
Main power switch function:
●
Position 1: The instrument is in operation.
●
Position 0: The entire instrument is disconnected from the AC power supply.
For details, refer to Chapter 2.1.1.6, "Turning the Instrument On and Off", on page 25.
