How to check the phase of the optical spectral components in Interconnect?

Hello all,
I have a simple system where an RF signal is fed to a phase modulator and modulates a CW laser light. My question is simple, how can I see the phase of the optical spectral components after the phase modulator? I would appreciate any help with this problem.
Here is a picture of my system:

Hello, You can visualize phase from Result view visualizer. From drop down list under “scalar operation” select angle(see the picture below). The spectrum analyzer only returns power by default however, which is why the phase is zero. If you change the plot format property of the analyzer from power to rectangular then it will return the real/imaginary parts of the spectrum, so you can get the phase.

Hi again,
I have a follow up guestion. I do not understand how to interpret the results from the Angle scalar operation and I didn't find any instruction. For example, I have the most simplest possible system: a Sine wave generator, and a Electrical spectrum analyzer. For the spectrum analyzer I use the rectangular plot format and the angle scalar function to plot the phase(?). My initial phase is 0 rad (first results plot), and pi/2 rad (second results plot). Could you please help me with the interpretation of the plots? How can I verify that indeed I see 0 rad, and pi/2 rad on the angle plot?
Kind regards,
