Error Accumulation - Reference
The Accumulation Setup window contains the following elements:
Activation Mode
•
Manual
Activate this option to configure the error detector to start and stop
accumulation when the front panel buttons are pressed.
•
Single
Activate this option to configure the error detector to accumulate over one
accumulation period and then stop.
•
Repeat
Activate this option to configure the error detector to accumulate over repeated
accumulation periods, whereby one period follows another immediately. There
is no "dead time" between the end of one period and the start of the next.
N O T E
Repeat will not create multiple measurement log files. The data for all repeating
periods will be saved to the same log file.
The accumulation mode cannot be changed while accumulation is running.
Measurement Log
• Prompt for File Name
Click this option if you want to be prompted for a measurement log file name
before each accumulation period begins. With this option you can select a new
file name for each test run.
•
File Name
Click this option if you want to enter a file name for measurement logs before
starting the accumulation. With this option you will overwrite the measurement
log file with each new test run. However, in Repeat mode, the results of all
repetitions will be appended to this file and no information is lost.
•
No Logging
Click this option to turn off measurement logging. Serial BERT will not save the
test results.
