Laser B Phase Problem

We will investigate this problem and do more thorough checkout. This is my suggestion:

RF - Please check that any changes on the Laser RF screen (Figure 1) shows up on the corresponding RF cable on the back of the Laser Seed chassis (Figure 2). For example, on the control screen turn ON/OFF the RF or change the value of GSet and confirm that it shows up on the right cable. Disconnect the cable from the chassis and connect it to a pwoermeter or RF analyzer. This way both the controls and the hardware parts of the RF system will be checked.
