All of the L4C interfaces (D1002739) were tested using the L4C Interface test plan at (T1600185). These were the chassis with serial numbers s1600252, s1600253, s1600254, s1600255, and s1600256. All of the channels were working fine except for the L4C 3 & 4 channels on chassis s1600253 which had the incorrect frequency response. On closer expection we noticed that this board was missing the capacitor located at C8 (see the schematic) for both channels. These capacitors have now been added. The chassis was retested and all channels are now functioning properly. I've attached the test reports for each chassis.
