M819xA AWG CMSI and DMSI Parameters
The following functional blocks are available in the Parameter Window to
generate CMSI and DMSI.
• Channel Configuration
• Channel Coupling – The channel coupling provides the flexibility to
couple the two channels. Depending upon the availability of
channels in a module, the channels can be coupled in the following
ways:
• Four channel Module: Channels 1/2 and Channels 3/4
• Two Channel Module: Channels 1/4
Use the drop-down option to select the channels. For example,
selecting “1/2” will couple channels 1 and 2. Once the channels are
coupled, the parameters values will be identical across both
channels.
The following block digram provides an example how to cable the
normal/complement outputs of AWG to couple channels 1 and 2:
Select “None”, if you don’t want to use the multi-tone functionality.
• Amplifier – This functional block has the following parameters:
• Output State – Turns on/off the state of the output.
• Termination Voltage – Sets the external termination voltage.
• Amplitude – Sets the amplitude of the output signal. Once, the
channels are coupled, this parameter will be in disabled state.
However, the value of this parameter depends on the value of
Amplitude 1.
