Elapsed Time
If Elapsed Time is selected, the test will continue for the time specified, then terminate.
PASS/FAIL Confidence
If PASS/FAIL Confidence is selected, the test will continue until the numbers of errors
encountered combined with the number of bits processed exceeds a specified confidence
level that the receiver is passing or is failing the test. The criterion required (maximum
error ratio) is specified in the Pass/Fail BER (bit error ratio) field, and the desired
confidence level is specified in the %Confidence field. Note that when this selection is
made, the actual length in time of the test may vary significantly from test to test, since
the actual number of errors encountered will affect the number of bits which need to be
processed to obtain the desired confidence level that the specification has been met (or
has been failed).
Max Errors
If Time or Max Errors is selected, the test will continue until either the time specified is
reached or the maximum numbers of errors is exceeded, whichever occurs first.
Time or PASS/FAIL
If Time or PASS/FAIL is selected, the test will continue until either the time specified is
reached or the Pass/Fail BER is achieved with the specified confidence level, whichever
occurs first.
Find BER Curve
If Find BER Curve is selected, the system will performed an automated jitter tolerance
test using a single variable (e.g., HF SJ Amplitude). You can specify the PASS/FAIL BER to
be used, and the parameter to be scanned. The system will then automatically scan
through the settings of the specified jitter parameter to identify the maximum setting
that the DUT can tolerate without exceeding the BER threshold specified.
