Vorsicht
Überschreiten Sie nicht die in der Produktspezifikation
angegebene Begrenzung der HF-Eingangsspannung. Sie
verursachen sonst eine Überhitzung der SSPA.
Nichtbeachtung kann zu einer bleibenden Schädigung der
SSPA führen.
Turn On
1 There are two ways to turn ON the SSPA:
Normal (M&C) Interface) — When operating the SSPA with the standard digital
M&C Interface the system turns ON as soon as prime AC power is applied. The
main voltage is turned ON by sending the appropriate command through the sys-
tem interface. Refer to the chapter titled
SSPA Communication and Protocol
for
command details.
Manual — In manual configuration the SSPA will turn ON the control system as
soon as prime AC power is applied. The control system is held in the reset mode
until the J1-Pin h is connected to either
J1-Pin Z or J1-Pin a. This allows the control system to operate normally.
Note
In manual operation the system is configured to transmit ON when the
prime AC power is on.
2. Connect and turn ON a test RF signal source. Slowly increase the
drive power to the amplifier. Monitor the RF output power through
the SSPA’s built-in sampler or through an external coupler.
Turn Off
There are two shut down modes.
Transmit OFF (M&C Interface)
When operating the SSPA with the standard digital M&C Interface the
main system voltage is turned OFF by sending the appropriate command
through the system interface. Refer to the chapter titled
SSPA Communication
and Protocol
for command details.
