Hello and thank you for the continued posts.

The Fluke Probes are matched to the Fluke meters based on the recommended 10 Mega Ohm specification.

Our PicoScope impedance is specified at 1 Mega Ohm which will effect your attenuation ratio.

Using the custom probe feature you can incorporate these Fluke probes with their 1000:1 and 10,000:1 attenuation values respectively, however the displayed values would need to be calibrated

For example: Create a custom probe for your 1000:1 probe and once complete measure the voltage of a known voltage source (12 V battery)

Depending on the value obtained via your new 1000:1 custom probe will determine the corrections you need to make to your custom probe settings.(Calibration)

PicoScope will have enough input ranges to cover the deviation and allow for your high end voltage measurements

The 3423 is also specified at 1 Mega Ohm impedance so the same custom probe settings will apply to both scopes.

Regarding the floating voltage values for the new 4000 series scope, unfortunately this is set at +-30 V from chassis ground and cannot be amended. With the onset of 48 V systems, this raises an interesting discussion and one I will present here at Pico.

There are no immediate plans to introduce a scope with such specified floating capability ( +- 50 V)

It maybe that the floating option is not the preferred choice for the development teams and that other options maybe thrown into the mix depending on demand and market trends.

All food for thought though, take care.......Steve

thanks, will get calibrating ...

I assume (oh no, not the mother of all @#@#up's) that the calibration will be the same for all 1 Mega Ohm scopes in your range (be it 3xxx series or new 4xxx) and that once created it will be happy on all without further change?

Will wait with baited breath for your development teams plans ... maybe we'll hear here first?

Thanks
Richard
