New Fluke 5730A calibrator

[quarks]

just received a email from "Fluke Calibration" about their new High Performance Multifunction Calibrator

you can find more details here:

I'm guessing all new products will come with a touch screen?

Old thread but ... today I went to my local calibration laboratory and they just had this one brand new on the bench.
I was able to play with it a little and it is just amazing.

today I did some calibrator comparison (see att. pic)

Nice to see my Wavetek 4808 is in the same league as Flukes most accurate calibrators. To bad Fluke canceled all Wavetek products.

I also added the Fluke 8508A to see the challange you have to face, even with very best calibrators   

BTW would be nice to have this Topic in the Metrology category

You have access to some impressive equipment
How come the Fluke 5720 and 5730 are just perfectly overlaying each other?
Has one be calibrated against the other one?
Or are they just that accurate?

the chart is only showing the 1 year datasheet specs (as noted in the headder of the graph).
Attached you find the 5730A and the 5720A Series II data I used. Both have the same uncertainties. That is why the graphs are overlaying.

Thank you quarks for the explanation, my bad for not reading it correctly.

Would be interesting to see the real comparison values between the calibrators.

Yes, that would be very interesting, but seems very unlikely to happen.

The Fluke 5720/5730 and the Wavetek 4808 are the very best multifunctions calibrators and seem to stay well below their specs over time.
But with difficult DUTs like HP3458A (or the even more challenging Fluke 8508A) they are still just not good enough. Therefore you have to have a "golden" calibrator which needs to be characterized at least within every 90 days. Afaik Fluke uses a 45day Intervall and is able to achieve 24h specs over time.

What I can do and have done is of course not traceable and therefore I do not know real absolut values. But when I compare my own gear, I read values against my own Standards and my best DMMs. But with this I still have good confidence, because most of my long scale DMMs agree within around +-1 ppm when checked against my very stable 10V DC reference.
