content: That's pretty close in price to some MicSig diff probes, though I don't know what price you're looking at on AE.

content: Currently offered at 131 usd and micsig DP700 for 180, so yes, does not make sense to buy themhttps://pt.aliexpress.com/item/1005009898930672.html?spm=a2g0o.productlist.main.1.5700b5b08NOrRj&algo_pvid=0d68e4af-5766-439c-ac57-02aba0022962&algo_exp_id=0d68e4af-5766-439c-ac57-02aba0022962-0&pdp_ext_f=%7B%22order%22%3A%22-1%22%2C%22eval%22%3A%221%22%7D&pdp_npi=6%40dis%21BRL%21767.62%21767.62%21%21%21930.00%21930.00%21%40210308a417575509659365333eccf2%2112000050517567040%21sea%21BR%212009187828%21X%211%210%21n_tag%3A-29919%3Bd%3A2aab8a2e%3Bm03_new_user%3A-29895&curPageLogUid=6L9w5a4N8e2H&utparam-url=scene%3Asearch%7Cquery_from%3A%7Cx_object_id%3A1005009898930672%7C_p_origin_prod%3A&gatewayAdapt=glo2bra

content: Micsig has a lot of models. Make sure you pick one that has the specs you need, and read the datasheet first to make sure.The DP700 is 70V or 700V max depending on the range.

content: Micsig is a well known brand and USB powered, so no need for a separate 12V power module and most modern DSOs have USB ports right on the front next to the BNC inputs, convenient power connection. Also the Micsig come with an assortment of adapters and nice carrying case.Best

content: Agreed, does not make sense to get this cheapo unknown when micsig can give me more bang per buck, if this probe was sold for under 80 usd or so, would be better suited

content: I've used their current probes... which I'm not seeing on their web site ATM, or at least not the BNC-output ones rather than the ones for their own scopes which have a DB9 connector that carries both the signal and power. It wasthis typebut that's from a unknown seller so could be old stock or who knows what. I got them for inrush current checking and they pretty much do what it says on the box. The fact that the Micsig equivalent was something like five time the price made it a no-brainer.
