Page 177: Bit Error Rate Measurements - Bert Block
R&S AFQ100A Bit Error Rate Measurements - BERT Block Bit Error Rate Measurements - BERT Block Introduction The instrument contains an integrated bit error rate tester which makes it possible to evaluate a signal demodulated and decoded by a DUT by measuring the bit error rate. A known PRBS-modulated data sequence (PRBS = pseudo random binary sequence) is sent to the DUT.
Page 178 R&S AFQ100A Bit Error Rate Measurements - BERT Block PRBS data To be able to detect faulty bits by a BER measurement, the data generation polynomial must be known. PRBS sequences are therefore used as the method for computing the data. These quasi-random bit sequences are repeated periodically, depending on the polynomial selected.
Page 179 R&S AFQ100A Bit Error Rate Measurements - BERT Block Interrupt-free measurement In the case of continuously generated signals that contain whole-number multiples of the PRBS sequence, the measurement occurs without interruption. Only the data and clock lines of the BERT interface are used for the measurement.
Page 180 R&S AFQ100A Bit Error Rate Measurements - BERT Block Data Enable The data signals usually contain not only PRBS data but also other data (e.g. sync and preambles) that would result in bit errors. The BER measurement for this data can then be interrupted using the Data Enable signal.

Page 185 R&S AFQ100A Bit Error Rate Measurements - BERT Block The measurement is not synchronized. No Sync Generally, a measurement cannot be synchronized until a clock and a data signal have been detected. If synchronization still does not occur, this may be caused by the following: The selected PRBS is not correct.
Page 186 R&S AFQ100A Bit Error Rate Measurements - BERT Block The Configuration section is used to select the type of measurement, the data source and the termination criteria. If the data is not cyclically continued, the measurement can be selectively interrupted and restarted. Certain data areas and frames that have been marked as faulty can be excluded from the measurement.
Page 187 R&S AFQ100A Bit Error Rate Measurements - BERT Block Enter the number of transmitted data bits to be checked before the Max. Data Bits measurement is terminated. This criterion terminates the BER measurement after the specified number of data bits, even if very few errors or none at all have been detected.
Page 188 R&S AFQ100A Bit Error Rate Measurements - BERT Block Sets the polarity of the feedback data bits. Data Polarity Note: Standard-compliant data inversion for PRBS15 and PRBS23 is performed automatically when the PRBS is selected. Data Polarity remains unaffected. High level stands for a logic 1, low level for a Norm logic 0.
Page 189 R&S AFQ100A Bit Error Rate Measurements - BERT Block Activates/deactivates an external restart of the BER measurement. External Restart The reset signal for the BER measurement is fed via the Restart input of the BERT interface. If the PRBS cannot be continued uninterruptedly, the BER...
Page 190 R&S AFQ100A Bit Error Rate Measurements - BERT Block Note: If the data is not enabled, the BER measurement is stopped completely. The identification circuit for Pattern Ignore as well as the PRBS generator of the BER measurement wait as long as the data is not enabled.
