Event Reports and SER

Standard 15-, 30-, or 60-Cycle Event Reports

Use the EVENT DIF command to retrieve differential event reports. There

are several options to customize the report format. The general command

format is:

EVE DIFz [n, Sx, Ly[–[w]]] (parameters in [ ] are optional)

Refer to Figure 9.4 for an example differential event report. This example

event report displays rows of information each quarter-cycle and was retrieved

with the EVE DIF1 <Enter> command.

Figure 9.4 Example Differential Event Report

The trigger row includes a > character following immediately after the last

analog column to indicate the trigger point. A

* character following

immediately after the last analog column denotes that the designated row was

used for the Event Summary currents. The

* character takes precedence over

the

> character when both conditions occur for the same row.

Table 9.5 summarizes the event report current columns.

where:

z = Displays results for differential element z (z = 1, 2, or 3)

n = Event number; defaults to 1 if not listed, where 1 is the

most recent event

Sx =Displays x samples per cycle (4 or 8); defaults to 4 if not

listed

Ly =Displays y cycles of data (1 to LER); defaults to LER if

not listed

Ly– = Displays from cycle y to end of report

Ly–w = Displays from cycle y to cycle w
