So if there was a fault that caused the bandwidth limit to operate unexpectedly (as suggested in other posts above) the scopes indication would be irrelevant.... but since the time constant is so different to the bandwidth limiters of the scope, that sort of problem can be discarded. As that poster is pointing out. --- End quote --- Sure but displayed signal rise time is very relevant to how the scope has been set. --- End quote --- So what does that have to do with your post? Or is it just shit-stirring bringing up heritage/quality? As I recall the bandwidth limits have dedicated LED indicators on the scope in question (or was that only the 6000?). |

Were it not the same in both directions I would suspect that some push-pull driver had lost its push or pull. But it is not that. Hard to guess without seeing schematics but I still reckon a hardware failure. --- End quote --- From the screenshot you can see that the bandwidth of the green channel is even as low as hundreds of kilohertz, and the datasheet says that the only selectable bandwidth limit of this oscilloscope is 25MHz. |

Having owned a few Agilent scopes myself, I'm quite sure that will come up with an error pointing into the right direction. --- End quote --- Yeah, self-test is always step 1 |
| Bud:
Does the response change with V/ change ? |
| HighVoltage:
How does it look like, if you set the scopes input channels to 50 Ohm and send a signal from a function generator that is also set to 50 Ohm? |
