VX-3200V Alignment

Introduction

The VX-3200V is carefully aligned at the factory for the specified performance across the
frequency range specified for each version. Realignment should therefore not be necessary
except in the event of a component failure, or altering version type. All component
replacement and service should be performed only by an authorized Vertex Standard
representative,or the warranty policy may be void.

The following procedures cover the sometimes critical and tedious adjustments that are not
normally required once the transceiver has left the factory. However, if damage occurs and
some parts subsequently are placed, realignment may be required. If a sudden problem
occurs during normal operation, it is likely due to component failure; realignment should not
be done until after the faulty component has been replaced.

We recommend that servicing be performed only by authorized Vertex Standard service
technicians who are experienced with the circuitry and fully equipped for repair and
alignment. Therefore, if a fault is suspected, contact the dealer from whom the transceiver
was purchased for instructions regarding repair. Authorized Vertex Standard service
technicians realign all circuits and make complete performance checks to ensure compliance
with factory specifications after replacing any faulty components.

Those who do undertake any of the following alignments are cautioned to proceed at their
own risk. Problems caused by unauthorized attempts at realignment are not covered by the
warranty policy. Also, Vertex Standard reserves the right to change circuits and alignment
procedures in the interest of improved performance, without notifying owners.

Under no circumstances should any alignment be attempted unless the normal function and
operation of the transceiver are clearly understood, the cause of the malfunction has been
clearly pinpointed and any faulty components replaced, and realignment determined to be
absolutely necessary.

The following test equipment (and thorough familiarity with its correct use) is necessary for
complete realignment. Correction of problems caused by misalignment resulting from use of
improper test equipment is not covered under the warranty policy. While most steps do not
require all of the equipment listed, the interactions of some adjustments may require that
more complex adjustments be performed afterwards.

Do not attempt to perform only a single step unless it is clearly isolated electrically from all
other steps. Have all test equipment ready before beginning, and follow all of the steps in a
section in the order presented.
