Connector Description
1 CLOCK
INPUT Error Detector clock input connector. Use this connector to provide a single-ended clock
input to the Error Detector. The input frequency range depends on the instrument model.
(Amplitude range: –2 V to +3 V, 50
Ω , AC-coupled)
2 DATA INTPUT Error Detector data input connectors. Use the Data+ and Data– connectors to input
differential data signals to the Error Detector. (Amplitude range: –2 V to +3 V, 50
Ω ,
AC-coupled)
3 MARKER Detector Marker input connector. Use this connector to accept a TTL-level Marker signal.
The signal can be used to synchronize error analysis with low-speed reference signals, such
as mechanical frequencies, packet boundaries, or loop markers. The minimum pulse width is
128 clock periods with a maximum repetition rate of 512 serial clock periods.
4 BLANK Error Blank input connector. Use this connector to accept a TTL-level signal to cause the
Error Detector to ignore errors. The Error Detector will ignore errors while this signal is active.
5 ERROR Error output connector. Use this connector to provide a 1000 mV pulse when an error is
detected. The minimum pulse width is 128 serial clock periods.
6 TRIGGER Trigger output connector. Use this connector to synchronize external equipment, such as an
oscilloscope to the BERTScope analyzer.
