We received the Tek 2024 scopes this afternoon, John helped me to install them in the rack. I connected these 2 scopes and TDS 520 to the computer with GPIB cables. The data can be acquired in real time, even it's not as fast as the scope response. I think it should be enough to obtain the data at 0.4 Hz. Actually we don't need to acquire the data for every shoot, we only need some special data for diagnostics. Previously Keith only used two channels scope to track the signals, which could provide enough information. Now we are using 10 channels to measure the signals.
