Vertex Standard VXR-9000 Service Manual

Rack Mount Repeater
VXR-9000
Service Manual
Introduction
This manual provides the technical information necessary for servicing the VXR-9000 Rack Mount Repeater.
Servicing this equipment requires expertise in handing surface-mount chip components. Attempts by non-qualified per-
sons to service this equipment may result in permanent damage not covered by the warranty, and may be illegal in some
countries.
Two PCB layout diagrams are provided for each double-sided board in this transceiver. Each side of the board is referred
to by the type of the majority of components installed on that side ("Side A" or "Side B"). In most cases one side has only
chip components (surface-mount devices), and the other has either a mixture of both chip and leaded components (trim-
mers, coils, electrolytic capacitors, ICs, etc.), or leaded components only.
As described in the pages to follow, the advanced microprocessor design of the VXR-9000 allows a complete alignment
of this transceiver to be performed without opening the case of the radio; all adjustments can be performed from the
personal computer, using with the Vertex Standard FIF-10A (or FIF-12) + CT-104A USB Programming Interface and CE60
Software.
While we believe the information in this manual to be correct, Vertex Standard assumes no liability for damage that may
occur as a result of typographical or other errors that may be present. Your cooperation in pointing out any inconsisten-
cies in the technical information would be appreciated.
After Lot. 30 of this transceiver was assembled using Pb (lead) free solder, based on the RoHS specification.
Only lead-free solder (Alloy Composition: Sn-3.0Ag-0.5Cu) should be used for repairs performed on this apparatus. The
solder stated above utilizes the alloy composition required for compliance with the lead-free specification, and any solder with
the above alloy composition may be used.
