If the instrument uses an internal reference source, the [10MHz OUT] connector can
output a 10MHz clock signal generated by the instrument and can be used to synchronize
other devices.
9. PULSE IN/OUT
The function of the connector is determined by the current mode of pulse modulation.
1) PULSE IN:
When the pulse source is "Ext", it is used to input external pulse signals.
2) PULSE OUT:
When the Pulse modulation source is "Int" and the pulse output switch is turned on, it is
used to output the pulse signal generated by the internal generator. The output signal is
related to "Pulse Mode", and can be set to "Single", "Double" or "Train".
10. SIGNAL VALID
When the RF output frequency or amplitude is modified, the RF output connector of the
front panel outputs the RF signal at the specified frequency and amplitude after a certain
response and processing time in the internal circuit of the instrument. In this process, the
[SIGNAL VALID] connector outputs an impulse synchronization signal to indicate the
validity of the RF output signal:
 High level (3.3 V): Indicates that the RF signal is being configured;
 Low level (0 V): Indicates that the RF signal is stable (effective).
11. TRIG IN/OUT
When PULSE trigger mode is "Int ", the connector can be used to output the trigger signal.
When the RF Sweep, LF Sweep, or PULSE trigger mode is "Ext", the connector is used to
input the external trigger signal.
