AutoTune™ for VX-P820/P920 Rev. B
C-1
APPENDIX C. Limits
The limits used to determine whether a test or alignment passes or fails are stored in Vertex Standard.VX-
P820/P920.Limits.ini. This file contains the default limits as defined by the radio manufacturer and generally should not be
modified.
However, in the event that the limits must be modified because of extenuating circumstances, the limits file may be
accessed from the main screen by first selecting a radio from the Radio Make and Model list box and then selecting the
Tools > Radio > Test Limits menu item. The limits file can be edited with a standard text editor, such as Notepad.
Modify the test and alignment limits with care. Improper use of the test and alignment limits can adversely affect
radio test results. It is recommended to back up the limits file before modifications are made.
The limits file is partitioned into various sections. Generally, each section corresponds to a specific alignment or test, or to
a specific point in an alignment or test. For instance, the TX Power High point is in its own section, even though it’s part of
the more comprehensive TX Power alignment.
When editing the limits file, make sure the format:
Name=limit
is followed precisely, with no embedded spaces between the equals sign and the test limit. Any improper editing may
cause AutoTune™ to incorrectly test or align a radio.
The following tables list the default test limits and alignment targets by model for Vertex Standard VX-P820/P920 radios.
