Can Eldo RF handle modulated signals?
A – Yes. Eldo RF supports digitally modulated sources and an analysis called ‘modulated steady-state’. The types of modulation supported are GMSK, GFSK, OQPSK, /4QPSK, MPSK, MFSK, EDGE, MQAM, OFDM and HPSK. The sources incorporate a low-pass filter (Gaussian, Square Root Raised Cosine or Raised Cosine), and they are driven with either an explicit pattern (user-defined bit stream), or a pseudo-random sequence (using a built-in pseudo-random pattern generator). Eldo RF also supports the standard PRBS used in test instruments. If the user is using an unsupported modulation format, arbitrary (generic) IQ modulators can also be implemented using the IQMOD source.
