Custom Modulation

For creating custom modulation, the signal generator offers two modes of operation: the Arb Waveform Generator mode and the Real Time I/Q Baseband mode. The Arb Waveform Generator mode has built- in modulation formats such as NADC or GSM and pre- defined modulation types such as BPSK and 16QAM that can be used to create a signal. The Real Time I/Q Baseband mode can be used to create custom data formats using built- in PN sequences or custom- user files along with various modulation types and different built- in filters such as Gaussian or Nyquist.

Both modes of operation are used to build complex, digitally modulated signals that simulate communication standards with the flexibility to modify existing digital formats, define or create digitally modulated signals, and add signal impairments.
