External Modulation Source AMIQSMIQCLOCKCLOCK SOURCEOUTPUTRESOLUTIONBIT ERROR RATETESTSets a clock rate, at which samples can be read out of the output buffer andtransferred to the output connectors I and Q via the D/A converters.Range: 5 MHz to 200 MHzSelection of the clock signal source (model AMIQ03 or higher).INT The internal clock is used. This is the standard setting presentupon switching on the unit or changing the clock.EXT_SLOW For external clock < 4 MHzEXT_FAST For external clock > 2 MHzOutput resolution of the signal. The resolution set for output cannot be higherthan for waveform generation.This menu enables configuration and performance of BER measurement.FREQ 100. 000 000 0 MHz LEVEL - 30.0 dBmFREQUENCYLEVELANALOG MODVECTOR MODDIGITAL MODDIGITAL STDAMIQ CTRLLF OUTPUTSWEEPLISTMEM SEQSAVE/RESELECTMODEEXECUTEEXT TRIFILTERLEVEL..MARKER.REFERENBIT ERRBIT ERROR RATE (BER) 2.3DATA BITS 10000000ERRORS 23TERMINATED BYNUMBER OF DATA BITS_______________________________________________________MODE OFF AUTO SINGLEEXECUTE SINGLETERMINATION ATTRIBUTESDATA BITS 10000000ERRORS 100PRBS 9 11 15 20 23 BitDATA POLARITY NORM INVCLOCK SLOPE POS NEGMASK POLARITY OFF LOW HIGHUNIT OFF % ppmFig. 2-233Menu AMIQ CTRL – BIT ERROR RATE TEST...(BIT ERROR RATETEST...)BIT ERROR RATE(BER)DATA BITSERRORSTERMINATED BYCyclical indication of the BER measured, ie the ratioof errors occurred to the number of data bitstransmitted.Number of data bits transmitted so far.Number of errors occurred so far.The cause of the indicated measurement result is:NUMBER OF DATA BITS The specified number ofdata bits has beenattained.NUMBER OF ERRORS The specified number oferrors has been detected.USERUser's manual interruptionof the measurement---- Measurement in progress1125.5555.03 2.366 E-9
