Sonda differenziale ad alta tensione per oscilloscopio Micsig DP10007 100MHz±700V Kit sonda oscilloscopio

D: May I see detailed specs? I missing information about capacitance of oscilloscope , i.e. 15pF , etc. And what is normal working voltage ranges, because in table is maximum input voltage only. Thank you.

KalponElectronics Hi!I just recorded this week a product review for it on Youtube. For DP10007 its 700 Volts mean peak to peak. (When there is not reference as RMS or Peak, Peak to Peak must be assumed as a rule. I recorded that part of the video just for you. With 247 Volts RMS AC you get 700Vpp input and 7Vpp output). The total input capacitance is 1.25pF in specifications. (That means 2.5 single end from any one of the test leads to ground). For sine waveform at 100MHz the image was perfectly reproduced and I got a -3dB voltage drop what is expectable. The product is what is written in the specifications and passed my tests too. The video will be online in February and one more video comparing DP10007 and DP20003 will be filmed too.

roberus This is very nice tool, if you need small function generator, buy it! But I think is suitable for hobby only. Control buttons are very small, be careful how often you are planning to work with.

roberus Hi,I'd like to ask you, is it possible to test symmetrical output of power supply, if I have i.e. /-50V? I hope output 1 and 2 from the device can be merged (one black and another one red pin). Please let us know. Thank you very much in advance. Robert

There is a nice review/overview https://www.youtube.com/watch?v=BhZgVdVELJU Also recommend to read https://www.eevblog.com/forum/testgear/et5410-or-dcl6104-or-a-third-programmable-electronic-dc-load-in-the-budget-cat/ Few notes/comments: - fast delivery (2 weeks over Holiday season, standard EU shipping for 23 USD) - great LCD, excellent viewing angles (no color changes from angles) - it is louder than necessary/ I would like but unfortunately most similar instruments are. Probably in a factory/lab does not matter but in home is annoying. But could be modified (see the link above and/or fan changed; it is a standard 80mm, 12V fan) - no indications when it can't regulate any more (e.g. in CC when the source cannot deliver the set current) - FW could be improved, but it works - perhaps the only / the biggest concern is the manufacturer support: ○ You can download user manual from http://www.czdingchen.com/custom/2 but it is only in Chinese (ok, Google translation helps here) and outdated (version 1.0, printed manual which came with the load was 1.1). ○ SW, drivers, etc only on Baidu disk. Requires Baidu account which I was not able to create. I have yet to try to sort this with the vendor/manufacturer. Eventually there might be some 3rd party / opensource (see EEVblog forums). ○ Question of FW updates. The load has front USB connector for FW updates but have not found any publicly available updates. Btw my load came with version v02.06.01.08. Overall very nice programmable DC load. Nice and solid build, in general I would recommend but beware of the support uncertainty.

roberus Hi.I have a question. I'd like to fix my broken logic board from iphone7, if I read your feedback, you do not recommend this microscope, do you? Thank you for your reply.
