BERT (Option UN7)
Bit Error Rate Tester–Option UN7
• T2 is a firmware handling time measured from the falling edge of a BER TEST OUT signal to the
falling edge of the BER MEAS END signal.
• T3 is a minimum requirement time measured from the falling edge of the BER MEAS END signal
to the next trigger event. T3 should be greater than 0 second.
The pulse output of the BER TEST OUT for the Nth- 1 test result ends prior to the falling edge of the
BER MEAS END signal for the Nth measurement; so you can use this edge to start latching the Nth
test result.
