Multi Frequency Modulation Tab

The Multi Frequency Modulation tab provides the overview of the sine generators for advanced modulation. This tab relates to the HDAWG-MF Multi-frequency and is only available if this option is installed on the HDAWG Instrument (see Information section in the Device tab).


  • Independent modulation of multiple sine signals on one Wave output

  • 4 sine generators per Wave output

  • Carrier configuration: frequency, harmonic, phase, amplitude

Access to all the settings of the sine generators in advanced modulation mode.

The Multi Frequency Modulation tab (see Figure 1) consists of 4 or 8 AWG Output Modulation panels corresponding to the AWG channels of the instrument.

When setting the Modulation mode of one of the AWG channels to Advanced, the corresponding channel can modulate 4 sine signals that are independent in terms of frequency, phase, and envelope signal. This is realized by de-interleaving the flow of samples from one AWG output into four signals with four-fold reduced sampling rate, multiplying each of them to an individual sine signal, adding up the resulting signals, and sending that sum signal to the DAC. This can be used to realize frequency-domain multiplexing or digital IQ modulation, see Digital Modulation for an example. Each panel of the Multi Frequency Modulation tab contains the settings of the four sine generators associated to this AWG output. The block diagram in the Output Tab illustrates how the MF Modulation units tie into the output signal routing of the HDAWG.
