Digital ModulationSMIQ2.10 Digital ModulationWith option Modulation Coder (MCOD) SMIQB20 provided, SMIQ can generate digitally modulatedoutput signals. Available modulation methods are ASK (amplitude shift keying), FSK (frequency shiftkeying), PSK (phase shift keying) as well as QAM (quadrature amplitude modulation). Baseband filteringand symbol rate can be freely set in a wide range.The modulation coder generates the analog IQ signals for the I/Q modulator of SMIQ from the digitalinput signals.IQ modulator RF up/down convertercos( ωt)OptionDataGeneratorOptionModulationCoderIRF OUTSMIQB11SMIQB10Qsin( ωt)Fig. 2-47Modulation coder in SMIQThe modulation coder works with digital input signals such as• clock signals (symbol clock, bit clock),• modulation data or modulation symbols,• control signals for envelope control and trigger signals.The digital input signals may originate from the following sources:• The modulation coder can generate clock signals such as PRBS data signals and simple datapatterns.• External clock signals, modulation data and signals for envelope control can be fed in via connectorsat the front or rear panel of SMIQ.• With option Data Generator SMIQB11 provided, an additional data source is available. This optionhas a 16-Mbit memory for modulation data and control signals. The memory can be extended to48 Mbit or 80 Mbit by installing one or two SMIQB12 options (Memory Extension).EXT DATA/CLOCKDATA MEMORYDIGITALIN/OUTDIGITALMODULATORIQPRBS GENERATORINT CLOCKData generatorModulation coderFig. 2-48Digital input signals of modulation coder1125.5555.03 2.86E-9
