Re: [volt-nuts] *WAY* too expensive for even Keysight to redesign
you could write your own front end using the IEEE 488 interface and make it what ever you want. excel can give you the graphic you are talking about and you have a lot more control over what you get than any canned fronted could do.

In addition many of these large companies buy up the small start-ups from the Scientist and engineers that created them as an alternative to in house RD. Once purchased they are quickly transisioned to the stock-holder driven model. Sadly in some cases I think the philosophy is to buy all the competitors and control the market to the point that they don't need to provide the same level of products, support, and service we enjoyed in the past since there are few alternatives. In this paradigm shift I think Keysight is better then most. I keep hoping they design a new meter to replace the 3458A or at least redesign the digital portion with a more freindly user interface, per haps a menu driven color touch screen and the ability to stored and display data graphically. Who knows they may have something in the works.

Had a signal generator long out of warranty, develop a problem with a front panel encoder. When calling for a replacement part they asked about why I needed the part... To make a long story short I ended up sending the signal generator in for service work and new NIST calibration, all free of charge. For something 7 years out of warranty, I was very pleased. Been buying a lot of Agilent/Keysight since then. Not saying one should expect this sort of service, but in at least one case they offered it!

[volt-nuts] How accurate is a fluke after 9 years
My Fluke 5700A calibrator was calibrated today after 9 years. It displays how much it deviated from the last calibration. For the both voltage references i got 0.0 ppm and for the internal 10k resistor -1.7 ppm. Only the amplifier for the 11-22 volt range drifted 1700 ppm for it depends on a voltage divider composed of two normal metalfilm resistors. These will be replaced by 2 vishay 0.01% resistors which are hopefully more stable.

Re: [volt-nuts] How accurate is a fluke after 9 years
Frans, Do you perform an in-house calibration with a 10V reference and 1 ohm 10k resistors? I have been studying the recommended calibration intervals of Fluke's 57xx series calibrators and I wonder how well the unit maintains its stability over long intervals between trips to a cal lab. Also, if you don't mind, would you give a ballpark figure for the cost of cal from your cal lab?

Re: [volt-nuts] How accurate is a fluke after 9 years
The Fluke 5700A and 5720A as well as the Wavetek 4808 and 4800A are pretty amazing I have seen several that appear to have been abused for years without a Cal and are still spot on. Same with many of the HP and Agilent 3458A's. It seems I see more broken then out of spec.
