Using a Fluke 123 as a O-Scope for a PSU Review

[SKYMTL]

As many of you know, I am presently doing a number of PSU reviews which have been going quite well.

I have run into a bit of a snag because my friend who does the ripple measurements on his o-scope is going away on a trip next month for between 2-3 months. So, I have decided to start looking for my own o-scope.

What I am looking for is something that can easily take ripple measurements from a PSU WITHOUT a load tester.

I have a line on a Fluke 123 Scopemeter:

Will this work for measuring ripple from a PSU??? Are there any other probes / add-ons that I will have to buy?

Thanks in advance.

Take it the digital route isn't going to work?

[SKYMTL]

It will. This is digital as well as it has a USB interface cable but I need to know if the Fluke is the way to go.

I am still considering the Stingray but the Fluke is...well...a FLUKE. :D

Hey this is {--M--} from NCIX!

The Fluke Scopemeter has a sensitivity which is only as good as 5mV/div. It depends how accurate you want your results to be. If you are just looking to go no further than maybe ~1mV accuracy, which I think is more than good enough for reviewing purposes, then this should be fine. Pretty sweet too that you can export waveforms to the computer and include them in your reviews.

It does come with test leads, you don't have to worry about purchasing any special probes. For the frequencies and voltage range you'll be dealing with, standard test leads will work just fine.

I'd say go for it.

I actually went and bought a Stingray. :D

Link to specs? I might consider getting one lol considering I'm in electronics eng and all (full-out scope is too much $$$).

Hmm actually nvm lol. Wouldn't be sufficient for my uses. The Fluke sounds a lot better for me.

They work well for capturing data from the BNC connector on the SM-268 and SM-8800's. The scope software is nice is a lot nicer than most full fledged scopes i have seen.

What are you needing one for?

[high_voltage_maniac]

It's the 250KHz limitation that's the problem. Some stuff I measure sometimes goes into the 500KHz+ range.

Yep not much can be done baout that then.

Sorry. They are nice otherwise.

Actually, I picked up the differential probes as well. Should be interesting to see how they behave....

hello,
help me please, I want to measure the transfer time, can fluke123 capture the time between 4ms transfer time.
