Operating Manual R&S SMIQ - Volume 1 - Rohde & Schwarz

BERT SystemSMIQ:BERT:SETup:DENable OFF | LOW | HIGHThe SMIQ has an input (data enable) allowing the temporary suspension of the BER test forprocessing data bursts or data interrupted by other data. This command configures this input.OFF Any signal applied to the input is ignored; all data are used for the BER measurement.HIGH If a high level signal is applied to the input, its data bits are counted and the bit errorsdetected and counted. If a low level signal is applied, the measurement is interrupted.LOW If a low level signal is applied to the input, its data bits are counted and the bit errordetected and counted. If a high level signal is applied, the measurement is interrupted.Example: :BERT:SET:DEN HIGH *RST value is OFF:BERT:SETup:MASK OFF | LOW | HIGHThis command is equivalent (alias) to the command :BERT:SETup:DENable described above.Example: :BERT:SET:MASK HIGH *RST value is OFF:BERT:SETup:IGNore OFF | ONE | ZEROThis command determines what to do with faulty data (frame errors) that were set to 0 or 1.OFF Pattern Ignore is not active.ONE Bit sequences consisting of 30 or more subsequent "1" data are not used (i.e. ignored)for the BER test.ZERO Bit sequences consisting of 30 or more subsequent "0" data are not used (i.e. ignored)for the BER measurement.Example: :BERT:SET:IGN ONE *RST value is OFF:BERT:UNIT SCIentific | ENGineering | PCT | PPMThis command sets the unit for displaying the error rate. It is only for display on SMIQ; it has noeffect on results queried by :BERT:RES?.Example: :BERT:SET PCT *RST value is ENG:BERT:STARtThis command starts a bit error rate test. The command :BERT:STAT is set to ON andBERT:SEQ to AUTO.Example: :BERT:STAR:BERT:STOPThe command stops an ongoing bit error rate test. If no measurement is in progress, thiscommand has no effect. :BERT:STAT is set to OFF.Example: :BERT:STOP1125.5555.03 3.32E-9
