7. External Trigger Input Connector
When the trigger mode of Sweep or “Swp-Sine” of LF
output is “Ext”, this connector is used to input the
external trigger signal.
8. Signal Valid Output Connector
When the RF output frequency or amplitude is
modified, after certain response and processing time,
the internal circuit of the instrument outputs RF signal
with the 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): indicate that the RF signal is in
configuration;
—
Low Level (0 V): indicate 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 sweep shape (“Triangle” or
“Ramp”) currently selected.
— When the sweep type is list, the default of this
output signal is ramp.
