Raymond! Fine to hear from you, The RT and BW on many TEK are conservative (unlike the Chinese scopes) and are often exceeded IF the test setup is optimized. tips for optimized RT : 1/ Use direct

Thanks for the explanation, Jon and yes, it's Raymond from the Netherlands. My remark about the rise time: I see a rise time of 200ps in your photo, which is quite surprising, even for a 7104 with
