I have a cold.
Right, glad we sorted that out.
I have a cold. On top of this I have Physics coursework. We all know coursework/lab work is a bitch, however I always grow to cope with it. This time I haven't though, because it just won't work how I want it to. I am supposed to be investigating crosstalk in a couple of wires. I decided I would test the variables of distance between the wires, the angle they lie to each other and the frequency of the original signal.
This would all be acceptable if I could actually observe it. It took me three sessions to find an oscilloscope that worked and fish out the other equipment I needed. And I spent the next two getting the experiment to work full stop. Now I can observe some crosstalk. The problem being though, I can only get 5mV of the damn stuff! When changing the frequency over a range of approx. 1kHz - 100kHz I observed between 1mV and 5mV - and it's 5mV per division!
So, my results are crap. And things just don't get any better in that there are no digital oscilloscopes left. And I need an A in Physics. Without coursework that would require me to get 120/100 in the two exam units!
I could compare it to being stuck in a hole with no spade, but someone will only point out Physics A levels don't have spades... Or something.
