Say you have to characterize a ferrite core, I think the gist of it would look something like: Wind two winding, primary for magnetizing the core, secondary winding for sensing.

- AWG drives primary, an amplifier is probably needed to get reasonable current into the primary to drive it into saturation.
- Measure current into primary + have user input number of pri turns and you get field strength (H), roughly.
- Measure and integrate secondary voltage + have user input number of sec turns and you get flux density (B), roughly.
- Plot in XY and you should have a BH curve.
- Stuff like saturation flux density, coercive force, remanence, hysteresis losses etc. can be calculated with maths.
- Some kind of offset/servo is probably needed to keep the secondary voltage integration in check.
- AWG allows measurement of B-H curves across different frequencies.

Something like that, idk.

Even if niche, that sort of stuff looks very impressive in marketing campaings, just say'n  ;)

Ultimately though, there is nothing special about same manufacturer intergated probes, they are interface nicers. It comes down the specs. A third party probe may actually have better performance than the ones from the manufacturer, but you might have to set it up maually which isn't a huge deal.

Well R&S UK delivered on their promise, early this morning UPS duly dropped off a demo bundle version of the MX04 with some probes I requested.

Just taken it out of its substanical protective packaging, not the usual R&S Germanic semi boat anchor build,but we are talking one tier above entry level for R&S, the inital feel and touch of the unit to me is a wee bit tacky. However we have to take into account of the price bracket and features/build costs and in use ability before making any comments. Size is nice its on par with the newer Siglents SDS2000 & 6000 models, Lecoy's Wave surfer HD etc. Front panel protector fits a lot easier than the afore mentioned units.

More over the weekend.

Here some "true" screenshots of the power analyzer option, the menus..

Hi Martin

 I have some of the Lecroy PA option  in use if you like.
