Bought from Ebay a Hantek T3100 (2KV 100MHz) oscilloscope probe to measure some things that may go over voltage for my regular 300Vrms probes, like the output of some CCFL power supplys, with working frequency in the KHz range.
Image 1: probe measuring a sinusoidal with aprox. 730Vpp, 260Vrms, 35KHz
(EDIT) Image 3: hardcopy from scope
With the probe calibrated with the traditional 1KHz signal from scope, as the frequency measured rises, an undershoot slowly increases. Attached a screen capture (image 2) with the above yellow trace from a TEK P2220 and the lower blue one, from the Hantek T3100, measuring a 4Vpp 1MHz square wave. For what I intend to use it, and for the price (€17), the T3100 is suitable. I'm just not a fan of the "unclipping" clip, but otherwise the probe seems well built.
I know the Testec are somewhat appreciated in the community, but they are more expensive and to spend more on a reasonable better probe, I had to put more thought on that. But if someone as any suggestion I'm always glad to ear it.
