Limit Testing
Limit testing is a quick pass-fail test using operator
defined limits or a stored trace as a minimum for
acceptability. Pass or fail will be displayed at the top of
the display and an audible tone can be enabled to indi-
cate a fail situation.
Limit testing is probably the most labor-efficient mode
for operating the AT-500. Since all the software set-
tings are retained when the tester is turned off, once
the limit test is set up its simply a matter of connect-
ing the next antenna system, turning on the power
and reading pass or fail.
