PPG Function

• Support for multiple bit rates: 9.95 Gbit/s to 11.32 Gbit/s, variable in steps of 1 kHz
• Output amplitude: 0.5 Vp-p to 2.0 Vp-p, variable in steps of 10 mV
• Offset: -2.0 V to +3 V, variable in steps of 10 mV
• Crosspoint: 30% to 70%, variable in steps of 1%
• Data and data bar: 2 outputs
• Trigger output for oscilloscope synchronization
• Port for external 10G clock synchronization input and 1/16 or 1/64 synchronization input It is possible to perform an error rate test with jitter deliberately added to the data pattern by inputting a synchronization signal with added jitter to this port.

Bit error rate test (BERT)

• A BERT is a type of code error measurement made through digital communication using a PPG as the signal source and an ED as the error detector.

ED Function

• The CDR signal extracts the clock from the data signal and performs synchronization when a data signal is the only input. In optical communications, the CDR function is a useful tool because the data signal is often transmitted alone.
• In addition to the CDR input port, there are ports for inputting separate data and clock signals. When these ports are used, the phases of the data and clock signals must be matched externally.
• Input ranges:
  0.1 Vp-p to 0.7 Vp-p (with CDR), 0.1 Vp-p to 0.6 Vp-p (without CDR)

Test Patterns

• There are two types of test patterns: pseudo-random (PRBS) patterns and program patterns.
• The PRBS pattern is selected from settings ranging from PRBS7 to PRBS31.
• In the standard configuration, the AQ2200-601 program pattern consists of 256 bits. A 64 Mbit option is also available.
