Axiom Home Page Forums General Discussion Home Theater VP-180 opinion needed (HP upgrade)

Nope Brendans. Its a cool idea to try a fluke. Just not sure the sampling rate would represent peaks in the frequency range of music. A scope would be better. Admittedly, I've never messed around with a fluke on anything but 60hz domestic voltages. Instumentation guys mess with the higher end meters more than we would.

Agreed, scope would definitely be better. The Fluke 189 manual claims it can capture transients as short as 250 uS, so I figured it should at least handle lower frequency signals OK.

Of course it says "with degraded accuracy", so not sure if that means +/- 10% or +1000/-99%...

In one of my first jobs out of school I had been working mostly on digital circuitry but got tasked to "go figure out how to fix the noise in that satellite receiver design". Tried to measure the 4 GHz signal coming down from the dish with a scope and a cheap probe, which didn't work anywhere near as well as I expected. Those cheap jumper cables don't work at 4 GHz either. At least I amused the RF guys for a while.
