ROCEDURES
Before applying prime power to the SSPA, verify that the following conditions are met:
•
The voltages of the station’s AC prime power matches those marked on the ID label,
which is 90-132 or 180-265 VAC (auto-ranging) for this unit.
•
The prime power station is properly grounded.
•
All connections are tight, no wires are pinched, and no other hardware has been loosened
during handling.
•
The main power switch on the prime power station is turned OFF.
•
The RF Input and RF Output are connected to a matched source and a proper load
capable to withstand full CW RF power, see Electrical Specifications.
•
The cooling fan is not obstructed.
WARNING:
The information presented in this section is addressed to technicians who have
specific training in, and knowledge of Microwave Power Transmitters. Inappropriate use of
the SSB can cause harm to the operator or equipment. Do not attempt the procedures outlined
in this section before becoming thoroughly familiar with its contents.
CAUTION:
Failure to verify these pre-power conditions may damage the power amplifier or
cause it to malfunction. Operating the power amplifier before verifying these items may also
void the warranty.
CAUTION:
Do not exceed –25 dBm input level. For input levels more than –25 dBm the
unit will be overdriven, will go in saturation, and will be irreversible damaged. Note that
damage caused by overdrive will void the warranty.
