Test Seconds When the Test Pattern is On, Test Seconds begins counting in one
second increments. When the Test Pattern is turned Off, Test Seconds
stops counting. Pressing the lette R resets the counter to zero.
Secs In Err and
Error Free Secs When the Test Pattern is On, a comparator looks at the received Test
Pattern and compares it to the transmit Test Pattern. The Seconds In
Error counter is incremented if one or more bits do not compare
during each second. The Seconds In Error counter increments only
once per second, regardless of the amount of bit errors during eac
second. The count in the Error Free Seconds counter is the difference
between the Test Seconds counter less the Seconds In Error counter.
Both the Secs In Err and the Err Free Secs counter in addition to the
Total Seconds counter are reset to zero by pressing R.
