I am using E9320 E-Series Power Sensors on an E4417A power meter. I am using continuous trigger mode with external trigger, and when the external trigger signal is pulsing, I see the power meter updating on both the A channel and B channel as I expect. When I stop the external trigger signal, the A channel stops updating as expected, but the B channel continues to update. It seems that the B channel is continuing to aquire data and update the display, even though it should be waiting for the external trigger. Does anyone know what is going on? I cannot see a separate trigger configuration for channel B, there only seems to be one global trigger setting, so I do not understand why the A channel and the B channel are not triggering the same way.
