7. External Trigger Input Connector
When the trigger type of SWEEP or “Swp-Sine”
of LF output is “Ext”, this connector is used to
input the external trigger signal. You can set the
polarity of trigger signal by pressing Trig Slope
to select “Pos” or “Neg”
8. Signal Valid Output Connector
When the RF output frequency or amplitude is
modified, after a certain response and processing
time, the internal circuit of the instrument
outputs RF signal with specified frequency and
amplitude via the RF output connector at the
front panel. During this process, the [SIGNAL
VALID] connector outputs a pulse sync signal,
indicating that the RF output signal is valid.
— High Level (+3.3 V): indicates that the RF
signal is in configuration;
— Low Level (0 V): indicates that the RF signal
is stable (namely, the signal is valid).

9. Sweep Output Connector
When the RF sweep function is enabled, the
[SWEEP OUT] connector outputs a signal (0 V
to +10 V) while the RF output connector at the
front panel outputs the sweep signal according to
the current setting. Each sweep corresponds to
an output cycle.
— When the sweep type is step, this output
signal is related to the choice of sweep shape
which can be set to “Triangle” or “Ramp”.
— When the sweep type is list, the default of
this output signal is ramp.
