ParticipantHi all, In LN-MZM where I can set the half wave voltage.
With Regards,

ParticipantHi Dhiman,
If you are referring to the voltage to make Null , Peak and Quadrature bias points, they are created using the bias voltages and their differece. I suggest that you have a look at the help section of the LiNb Mach Zehnder modulator for more precise information about how to set the values.
Regards

ParticipantThanks alistu, The 3 different configuration u have attached have difference output but still not clear about the half wave voltage.
With regards

ParticipantThe three different configurations have different bias. As far as I know, the half-wave voltage is the voltage needed to have a phase change of pi. For this purpose, I think you should use the settings for the null operating point. Please notice the sine generator bias in the three settings.

ParticipantHalf wave voltage is nothing but the switching voltage which decides the slope of the transfer function of the modulator.
To bias the modulator in quadrature, keep the switching voltage at 4volts (for example) and the bias voltage (either 1 or 2) at 2 volts. The modulator will generate double sideband full carrier signal when the phase shift between the two is 180 degrees. Let me know if you need furthur help.
