9.6 Pulse interface
The pulse interface is required for the pulse feature, which allows the
Synertia® RF generator to pulse the RF output signal depending on an adjustable pulse
frequency and duty cycle. The pulse frequency defines the length of the pulse period and
the duty cycle is defined as the percentage of RFon to RFoff time in one pulse cycle.
The Synertia® RF generator can be configured as a pulse initiator or receiver in a setup
with more than one generator.
You can configure the generator as a initiator or a receiver via the wiring of its pulse input
or output.
• Pulse initiator: the “Pulse Out” socket is connected. In this configuration, the
Synertia® RF generator delivers the Pulse signal to one or several receivers. The
receivers pulse their RF output signal synchronised to the initiator if they are
configured accordingly.
• Pulse receiver: the “Pulse In” socket is connected. In this configuration, the
Synertia® RF generator follows the pulsed RF output signal of any initiator in
pulse frequency and duty cycle.
You can operate several Synertia® RF generators in daisy chain, which means that you
have to connect both sockets (“Pulse In” and “Pulse Out”) to other generators. The result
is that this generator on the one hand acts as a receiver of a first initiator in this chain
and at the same time is the initiator of the next receiver in this chain.
In some applications it is necessary to have a specific phase relation between several
pulsed RF generators. Therefore, you can adjust the phase delay between the pulse input
signal and the pulsed RF output signal of any Synertia® RF generator by issuing a
command via any digital interface.
The Pulse input signal can also be used to trigger any pulse pattern of the
Synertia® RF generator's RF output signal. The only limiting factor for the configurable
RF output pulse pattern is the pulse period duration of the Pulse input signal.
To activate and deactivate the pulse feature and to set the corresponding parameters,
use the associated commands via any digital interface of the Synertia® RF generator. All
settings should only be applied in relation to the physically realized chain architecture.
Use suitable high-quality, double-shielded coaxial cables to connect the Pulse
input/output.
Make sure that the connections between cables and connectors are tight. The cables are
not provided by Comet.
For the technical data of the pulse signals (e. g. pulse frequency, duty cycle range, time
resolution or rise and fall times), refer to the data sheet.
