Operation
It shall be performed by authorized personnel prior to maintenance and/or repair.
Procedure
Verify that the installation procedure described was completed. A complete physical check of the
customer’s system is suggested.
The output power available at the output waveguide flange is extremely
hazardous. Under no circumstances should block up converter be
operated without the waveguide feed or a high power load attached. Do
not operate this equipment in the presence of flammable gases or fumes.
Failure to observe this precaution will result in personal injury. Safe
and careful installation of this block up converter will eliminate the
possibility of accidents and provide years of top performance.
Verify the antenna feed waveguide connection is properly done before the block up converter is
energized.
The block up converter can withstand any source or load VSWR.
However, the block up converter will meet all specification requirements
only if the source/load VSWR is sufficient. Normal operation is not
possible if the antenna feeder VSWR is greater than 2:1.
Turn ON the power and allow a warm up period of twenty minutes before operating the block up
converter. This will assure stable gain and power. The block up converter can function with a coupler
when a direct measurement of the output power is made.
