General Information
Specifications
POH: J1, C2, G1, F2, H4, Z3, Z4, Z5.
Any of the overhead bytes listed above
is selected and a BER measurement is
9
performed using a 2
-1 PRBS inserted
into a 64 kb/s channel. Single errors can
be added to the test pattern. Error
count, error ratio, error free seconds,%
error free seconds and pattern loss
seconds are measured.
Frequency measurement: Frequency
displayed in Hz, 1 Hz resolution. Offset
displayed in ppm and Hz.
Graphics and Logging
Graphic display or printout:
Barchart (results versus 60 time
periods) for current or stored
measurement period.
Bar resolution: 1 second, 1, 15, 60
minutes.
