Hmm I'm surprised you think it's an easy task since you're part of the industry. I've designed the actuators to do these sort of testing and I agree that this part is pretty straightforward since it's usually pneumatic for the response time. However, the instrumentation and processing side is never straightforward, especially in production. I'm guessing the trade secret is probably some sort of measurement device or some special pressure balance system on the actuators.
