Servos Spektrum H3050 & Servo Centering Tool

I recently purchased the Turnigy CCPM servo consistency master gadget and upon using it on my H3050 servos, I noticed that they had some chatter whilst connected. My cheap blue 9g servos don't do this. What is the reason?

If they are digital, then that is why. Digitals are quite noisy.
