Measurements

BER Measurements

Three simultaneous BER measurements (Totalize, Window and Test) displayed as:

BER	9.9E-01 to <1.0E-16
Totalize	0 to 99999999, then 1.0E8 to 9.9E36
Totalize Mode	BER since power on or reset
Window Mode	BER over sliding window,
	programmable in time (1-sec to 24 24-hrs) or bits (1E-8-1E-16)
Test Mode	BER over time of test, programmable in time (1-sec to 24-hrs). Additional
	calculations include ES, EFS, TES, SES, DM, US, and LOS.
Frequency	System Clock Frequency, 10 KHz resolution
History Indicators	SYNC loss, Bit Error, Phase Error, Power
