10. Pulse Signal Input/Output Connector
The function of this connector is determined by the
current working mode of the pulse modulation.
PULSE IN:
— When the modulation source of Pulse is
external, this connector is used to input the
external pulse signal.
— When the modulation source of Pulse is
internal and the trigger mode is “Ext Trig”, this
connector is used to input the external trigger
signal.
— When the modulation source of Pulse is
internal and the trigger mode is “Ext Gate”, this
connector is used to input the external gated
signal.
PULSE OUT:
When the modulation source of Pulse is internal
and the switch of pulse output is “on”, this connector
is used to output the pulse signal of the internal
generator. This output signal is related to the choice
of pulse mode which can be set to “Single”, “Double”
or “Train”.
11. I/Q Modulating Signal In/Out Connectors (option IQ-DSG3000)
When I/Q modulation type is “external”, it is used to
input the I (In-Phase) baseband signal of I/Q
modulation.
When I/Q modulation type is “external”, it is used to
input the Q (Quadrature Phase) modulating signal of
I/Q modulation.
It is used to output the I (In-Phase) components of
the I/Q modulation of the built-in baseband
generator.
It is used to output the Q (Quadrature Phase)
components of the I/Q modulation of the built-in
baseband generator.
