content: I am about to be the proud owner of a Siglent SDS1104x-e and wondering if anyone has any recommendations on a reasonable but low cost differential probe for this. Mainly used for mains PSU and Audio Amplifiers (perhaps some tube work down the road). Not looking for massive voltages but a few hundred would be good.

content: The Pintek DP-25 entry level diff probes are OK if you can find a local source.http://www.pintek.com.tw/product_detail/landersound/index.php?Product_SN=19265&Company_SN=6002&Product_Site_Classify_SN=17072Dave offers these:https://www.eevblog.com/product/hvp70/Otherwise for non demanding tasks Siglents ISFE:https://siglentna.com/product/isfe-isolated-front-end/

content: Look for the ones from MicSig. Cheaper and in some cases better compared to what Tautech suggested.

content: Agree with Nico, only downside is that the least attenuation is 50xhttps://eleshop.eu/dp10013-differential-probe-100-mhz-1300v.html

content: I would also recommend the Micsig DP10013. I've had mine for a few years and used it daily while working on ultrasonic arrays. The price is reasonable for the performance. Most scopes can customize the channel attenuation to match the output of the DP10013 (sorry don't own a Siglent scope)

content: +1 For the micsigs, i have a handful of themhttp://www.micsig.com/html/41.htmlI'd get a DP10013 and a DP10007You could get two of them and use which ever the better case is for the attenuation and voltages

content: You can buy Tektronix 1103 PSU, and use any Tekprobe with any scopes (some needs 50Ohm input support for scope)Tektronix probes are really cheap on Ebay!!i bought 1103 for 120$ and P5205 for a 100$(with cut on High voltage wire) wire was replaced and i got universal PSU for cheap probes+ Greate 100MHz probe.. Same LeCroy is over >>500$..

content: Quote from: Elasia on December 04, 2020, 11:50:11 amI'm a technical professional, I revise this probes during the wire "replacing" ant test the HV input part for leakage.There's simple hi-Ohm dividers on inputs there no chance to broke with possible operator harms..Of course, i do not use, just purchased as a "parts" probe, on High Voltage, only after check)).
