New low-cost ($170) 100MHz Differential scope probe from Micsig

[mikeselectricstuff]

Micsig just launched a new 100MHz HV differential probe

According to their mailshot

Dear customer, We're honored here to introduce our new product: Micsig High Voltage Differential Probe! We tested it compared with Tektronix P5200A, it works extremely good

They did offer to send me one, but I just don't have time at the moment..

Same here. I'm wondering whether it is a rebrand or their own design. In case of the latter it would be nice to do a teardown. Also I would like to be able to plug in a banana to BNC connector instead of the flying leads to be able to use it up to 100MHz.
Still the USB power and loop through is a nice touch.

Too bad it's X50 and X500.
Max voltage is not much higher than the more useful X10/X100 probes.

Looks great, they should send me one. I'll do a review!

Yes, just noticed that. Could be be limiting for measuring lower level signals, especially on scopes that force BW limit on at low mv/div settings.

And they offer it for $100 if bought with oscilloscope... I couldn't resist.

Seems like a very good thing to have around.

Literally could be a life saver for some people!

Note that $170 is the introductory offer. According to the AliExpress listing the normal price is $283, which is less of a deal.

Also I would like to be able to plug in a banana to BNC connector instead of the flying leads to be able to use it up to 100MHz.

The flying leads are fairly short and can be twisted, so I imagine they work well enough up to 100 MHz. I guess they could have used an insulated BNC connector, but accessories for those are kind of rare and might be inconvenient for field work. They may also not be much better for common mode rejection because of their unbalanced nature. And would invite even longer leads. At that point you might as well be using a stand-alone differential amplifier.

Damn, I bought Micsig scope over a week ago. Should've waited a bit.

Hantek Version around the same price also x50 x500: $188

I like that for the 5V you can plug it into the scope's USB port (I presume). Much better than battery alway dying.

[alm]

And more versatile than proprietary probe power connectors as often used by brand-name probes.

We will have to wait for reviews to see about performance and safety. I am especially curious how the common mode rejection ratio (CMRR) will fare at high common mode voltages (voltage coefficient in the attenuators). But maintaining its CMRR across the common mode voltage range might be expecting too much from a cheap differential probe.

I'm sure they would give you the discount. Just ask them.

I seen the same probe yesterday on Aliexpress and i was curious.....
So i wait for some more info/opinion and almost sure i ll buy one because i've need one more....especially in this price range is really interesting.

I am sure you can still get it for $100 if you ask micsig.

At a $100 ask if you can buy two.

[Dubbie]

Yeah, the first thing I thought when I got Daves probe a week or two ago... "I wish I had two of these"

[TheSteve]

If they did start selling them at 100 bucks they would be backordered pretty darn fast.

[nidlaX]

This is supposed to be their own design, not a rebadge.

Would anyone with high voltage / transient testing equipment like to do a teardown / review of this probe? joeqsmith perhaps?

Kudos for the 5V power input, as it can be powered by ordinary cellphone's power bank.

More so for the USB jack on the side so they can be daisy chained. 
Someone was using their gray matter. 

[Hydron]

Very tempting... just wish it had been out long enough for some reviews. Thanks for the heads up!

Has anyone (maybe Mike?) had experience getting Micsig stuff into the UK? If it's likely to get caught up in customs with extra fees and delays then it might be easier paying a bit more and buying within the EU.

I've never had customs issues cause significant delays - depending on the courier, they either contact you for payment before it arrives in UK, or send an invoice later.  For higher value items, the brokerage fee is relatively small compared to what an EU distributor will charge as their markup. The rest is VAT which you'd pay either way. I don't recall if the full value had been declared.

[lukier]

I've messaged Micsig on Aliexpress, well see if I can get the promo deal.
If I get the probe I can write a mini-review here and maybe compare it with Tek P5205 which I got from eBay "for parts or repair" (cable cut) a while ago.

not enough grey matter. that thing need mains supply or power bank around in order to work. i wish someone has enough wisdom of using 2 rechargable li-on stacked inside (preferably 18650 size hence easily replacable) 7.2V with charging circuitry (from 5V USB) that doesnt block operation during charging (ie charging while probing)...
