Measurement Reference
Two vertical markers indicate the ingress limit frequency range for
the violation detected. One horizontal marker indicates the limit
amplitude threshold of the detected violation.
You can access subsequent and previous violation results by
selecting NEXT RSLT and PREV RSLT respectively. PREV RSLT is
not displayed for the first result in a record; similarly, NEXT RSLT
is not displayed for the last result,
The VIOL CNT value changes after all the violations for the sweep
have been displayed and is moved by the number of violations
detected for next sweep. For example, one interpretation of Figure
3~25 is that there were five detected violations for the first sweep in
the record displayed. and the violation shown is either the second,
third, fourth or fifth. The number of violations detected per sweep
depends somewhat on the number and type of active limits. If only
