Even now, it remains unclear which probes can be used to which extent due lack of documentation. I.e. it's quite common for scopes to get a firmware update to properly support an active probe. Actually this just happened for the SDS5000X for the only active probe available.
In the time I've had my
SDS5054X SDS5104X (1yr+) the SAP1000 probe has always been supported and there have been 2 FW updates in that time.
However as you may have noticed a 2nd version of the latest FW was released as 10x attenuation for SAP1000 was omitted but now corrected which begs the question why were probe settings changed at all ?
My take on this is, it was while support was being added for LeCroy and possibly Tek probes too as these active probe adaptors would have been in their final stages of development.
I wondered at the time why the SAP1000 attenuation was mucked up but now with these adaptors released it all seems to fit together.
I would think that some special features like calibration, auto-zeroing and the like might not work "out of the box".
Possibly but as above this may already have been addressed and quite possibly a wider range of LeCroy ProBus probes might be supported at some later date on request.
Besides, LeCroy active probe connectors a quite long/deep so when connected on top of that adapter, this construction will reach an impressive length/depth and thus cause a considerable amount of leverage. I hope the mechanical construction is sound but it will still look weird.
Yes of course this is a concern however I doubt any are as heavy as a Tek 134 probe amplifier that hangs just on a BNC whereas these active probes are of much less weight and snug up against the front panel for much better mechanical support.
