11 Record Export Utility
11-4 TESLA LITE User Manual D03283R01.10
Version The Version field lets you select the revision of COMTRADE stand-
ard to produce. COMTRADE has been an evolving standard and a
number of changes have been made over the years.
1991, 1999 and 2000 COMTRADE versions are supported.
Format The Format field specifies that the data in the COMTRADE file
(ASCII or BINARY format).
ASCII data has the advantage of being usable by simple text editor
and spreadsheet programs, but results in a significantly larger
record relative to binary format.
BINARY format is therefore recommended if the software package
you will be using the data in supports binary format COMTRADE.
Selecting Channels
(Exported Channels) You must select the channels from the record that you want to
include in the output file.
For convenience, the digital data recorded is classified into:
• High Speed: Analog and external digital input channels sampled
at the high speed transient data rate.
• High Speed (480/sec): Analog and internal logic channels pro-
duced 8 times per cycle.
• Low Speed (60/sec): Analog input channels sampled at the low
speed swing data rate.
Select the desired channel from the list with a left-click.
Multiple channels can be selected using standard Windows selec-
tion actions (click + Ctrl or Shift keys).
