My first scope was/is a Tektronix 2215. It was a gift, perfect for a noob, but it came without any probes.
I researched probes, before buying a set and learned that the probe's bandwidth rating should match the scopes bandwidth rating. And, that you did not want to buy probes with greater bandwidth capability than that of the scope. This was confirmed through multiple sources. The reasoning and sources are long forgotten.
Now, I have watched this video:
In it, the Rhode & Schwarz engineers plainly state, repeatedly, that the probe's bandwidth should be a minimum of 1.5 x Scope Bandwidth; @ 6:34 and other times.
So, which is it?
And, are probes marketed with their bandwidth being stated as appropriate for X scope bandwidth? In other words, a probe marketed as a 60MHz compatible probe actually has 90MHz of bandwidth capability? If not, I bought the wrong probes... Given my first research, I bought 60MHz probes, as the 2215 has 60MHz bandwidth capability.
My new Siglent SDS1104X-E scope, having 100MHz bandwidth, comes with PP510 probes, having x10 bandwidth of 100MHz.
Thank you.
