5.3.1 Power-on
Question:
The equipment is turn off?
Answer:
• When you have performed all of the connections described in the previous
paragraph, power on the amplifier using the suitable power switch on
the rear panel. Power on the pilot exciter switch on the front panel.
Ensure that the
ON
light turns on. Start up informations should appear briefly on
the display, quickly followed by the main readings. If RF output is disabled, these
readings will be zero.
5.3.2 Frequency lock check
Question:
The equipment doesn’t work correctly?
Answer:
• Ensure that the LOCK light turns on. It indicates the PLL is locked to working
frequency, wait at least 15 seconds from the power on of PTX1000DDS .
5.3.3 Power check
Question:
The equipment doesn’t work correctly at the power set up?
Answer:
• Ensure that the INTERLOCK light turns off. It indicates that no external interlock
signal inhibites the delivering power from exciter.
• Ensure that the F.BACK light turns off. In counter case indicates the foldback
function is operating (automatic reduction of the delivered RF power). To restore
the right operation, connect a proper load, or antenna, to the exciter.
• Check current RF output setting and enable output (if not already
enabled) following menu path Admin ⇒ RfSet ⇒ Pwr ⇒ ON . Otherwise is
possible enable the output power directly from main menu.
Output power can also be set in a Pwr OFF condition; in this condition, (Fwd) output
power reading on the display will be 0 (zero), that will be delivered the moment
you switch back to Pwr ON state.
