Squeezer p-pol

I couldn't find the p-pol laser and sidebands on the spectrum analyser (figure 1). I made sure the DDS board was reset properly, the lasers had proper current and temperature, and the beam was going into the fiber. I also tried disconnecting and reconnecting p-pol cables that I could see. Maybe something is disconnected elsewhere?

CC seems ok (figure 2)

The beatnote can be seen with lower reference level (10dBm) as shown in the attached picture.
