AD3 probe compensation for newbie ?

[nurber3]

Hi Forum.  I see the Waveforms directions for  performing this, but I'm realizing I have only two passive probes and believe I cannot accurately compensate one probe using another probe connected to AWG output ?  BNC pins do not pass-through to MTE header so although I can ground to MTE header I'll need to find another way to get to pin of AWG ?  Any resources on the subject welcome.

Thank you

you can remove the hook and plug the probe directly into the center of the bnc connector for the AWG, and connect the ground with the ground clip

Hi forum.  I've performed the compensation on two identical passive probes that I own.  Unlike a few videos I watched and the images from replies to this thread I'm unable to get a flat response using the trimmer.  I believe this trimmer is referred to as LF.  There is also another trimmer at the BNC which I think is referred to as HF, but I can find nothing about it and it doesn't accept the included flat head that works on LF trimmer so I'm not sure if I should adjust.  Cheap probes or can I do better with HF trimmer ?  First network analyzer I've ever used, very cool feature.

Hi @nurber3

Probably the probe is not compatible with this device, the compensation range is not enough.

Thanks for answering.  I see a compensation range of 10pF - 35pF for the probes in question ( specs below ) which I'm guessing inadequate ?  Are the specifications required for probes published somewhere on site ( I couldn't find ) ?

Hi @nurber3

The compensation range of that probe seems to be insufficient.
The following 1/10x probe should be compatible with AD1,2,3
