Pattern Capture
The M8020A/M8030A/M8040A Analyzer captures the data received from
the device under test. The captured data bits are displayed in the pattern
capture pane in binary or 8b/10b symbol coding. The received data is
compared with the expected data and the errored bits/symbols are
highlighted. The captured data can be saved for post processing.
The maximum capture memory for M8041A, M8051A, M8061A and
M8045A is 2 Gb and for M8062A is 1 Gb. However, it also depends on the
holdoff length which represents the amount of symbols in which the
trigger events will be ignored.
