New MicSig/EEVblog DP10007 HV Differential Probe

<< < (24/38) > >>

ojete:
It seems there is a new probe from Micsig which looks very good.

Output Voltage ≤1.5V, maybe not a low noise.

I've been looking at buying a new diff probe recently.

It strikes me that this DP10007 is not much good for off-line SMPS work as it is limited by its maximum differential and common-mode voltage specs. A typical modern off-line switcher with PFC is going to be switching about 400V and depending on the circuit topology it is fairly common to see twice that across the switch, i.e. 800V.

On the other hand, the 1300V spec of the DP10013 is possibly higher than it ideally would be, giving poor SNR.

It seems to me that the optimal is somewhere between the two. If I was Micsig I'd probably have aimed at about 850-900V.

It does lead one to wonder what the target market of the DP10007 is? Maybe they want you to buy both DP10007 and DP10013 to cover all scenarios. Sneaky.

Last saturday my DP10007 arrived, didn´t test it so far.
Looks good so far, if it´s usable the price is insane cheap, so I wouldn´t worry to buy another one to cover higher voltages.

The best configuration IMO is a 1400Vpk 20X design with the 7 volt output.  Sapphire makes one, but apparently people are put off by the 'odd' 20X attenuation.  The DP10007 is safe to 1400Vpk just like the DP10013, it just saturates the output.  I have the DP10007, it works and is handy at times, but I don't regard it as quite a pro-quality instrument and am glad I got it cheaply.  I would gleefully trade it for a Probemaster 4231 if I could.
