Scopes with isolated inputs

Raveninghorde · 2012-05-23T08:23:43+00:00

I need another scope.Currently I'm using an old real time scope and a Fluke Scopemeter withisolated inputs. The Fluke doesn't work well on SMPSU, too much crapcouples between channels.I'm looking for 4 channels with isolated inputs, ideally not tooexpensive. Any recommendations?

My Audi gives me short but insulting lecture displays when I start it up. Once I got a warning that I should call an 800 number immediately, so I did. It was an attempt to sign me up for Sirius satellite music junk.

I sure wish I could reprogram this thing. There's a lot of idiotic stuff I'd turn off. It is "over engineered" in the worst sense of that term. Mo's Honda Fit is simple and brilliant by comparison, except for setting the clock of course. (I saw it on the web and it looked so cool I bought one online without either of us having driven one. She loves it. The Fit may be the best car in the world.)

I have a couple of 2k volt probes I paid under 100 for each set.

The deal breaker comes when you need high bandwidth with high voltage. If you don't need high bandwidth probes when doing HV testing, which is most of the time, then it's not so bad..

The probes I got are rated for 250Mhz and made in germany. But since that purchase, I have not been able to find them any where or probes of that BW and voltage for that low price.. But they are still much lower priced ones than what you have seen.

At work, we have a 60Kv at 250 MHz that we use from time to time. that can be used on a DMM or Scope.. That one cost some where around $5k.

RS do a high voltage probe for around =A330, they work great but the spring= tip breaks easily so I have to replace them every 12-18 months.

I found these people very good on their pricing and good quality, too! I got my last set of semi HV probes from them 100x fixed types, gold plated for under $100 each.

How do you do 100/300/500MHz (faithfully) with leads that long?

I had a similar problem with my cell phone a couple of weeks ago, when trying to take my cable box back to the cable company. The thing kept telling me to make a legal U-turn. To do so I had to go through a *major* (six lanes on each road, with construction on four lanes - major traffic mess). I finally turned down one street, then it gave me instructions to go around the block, where I found the place. I guess sometimes you gotta give it another dimension to work in. ;-)
