Micsig DP10013 High Voltage Differential Probe 1300V 100MHz 3.5ns Rise Time 50X/500X Attenuation, Tektronix P5200A P5205A P5210A,White

Playing with mains voltages (240v RMS in the UK - that's around 680v + peak to peak, which 'aint no joke!) should be undertaken with a great deal of care. I have used my standard oscilloscope probes for measurement in the past, but there's a chance that a slip up would destroy my 'scope. Using a differential probe will reduce that possibility significantly. That was the main reason for purchase but this device allows other measurement possibilities too. Exploring a circuit where I want to look at some electrical features that are in reference to a common ground I can use the standard scope probes. I may want to look at other elements in the same circuit that do not share the same ground, however. With the probe I can make both measurements simultaneously. Enough of the purchase justification already.... On with the review. The probe requires an external power supply; a standard USB output connected to a separate PSU would work. Given that this is such a ubiquitous power source however, and with the isolation on the USB power supply socket in evidence, i.e. there's no continuity from the input or output leads, you can power this from your PC, laptop or even from the 'scope if required. My Rigol (like most scopes these days it would seem) has a USB socket on the front of the device that powers the probes nicely. The kit comes complete with a standard Male USB A to Male USB B cable so it can be plugged in without recourse to seperate PSU's immediately and with no recourse to worrying about batteries. There is a USB socket on the DP10013 that allows you to plug in and power additional devices, which is good. However, when connected to the 'scope for power, plugging a USB stick into the DP10013 unit, one that works perfectly well when plugged directly into the 'scope, does not work. The power is there, but the data connection does not appear to be; you can't use the port on the probe to attach a USB key, which is annoying. In practice, I do all my work on a bench, so I'll either use a USB connection for my PC, or if I'm using it for high voltage measurement but still need the capability to store screenshots, I'll use a stand-alone USB power bank to power it just for extra isolation. This issue erk's, however. It will be annoying if i was ever in the field. Having this port available but not able to use a data key in it makes me wonder what the designers thought this would be used for? Data key issues aside, the device is easy to use and seems to be completely compatible with my 'scope (Rigol DS1054). The paperwork states that any 1M Ohm input will be, which will be most oscilloscopes I would think. Given the quality of measurements I'm making, spending many hundreds on a similar device was simply not an option for me. This device, in comparison to other high voltage differential probes, offers great value for money. It gives me the extra safety and advanced functionality I need without breaking the bank and offers a higher bandwidth then other items at around the same price. It comes with an excellent hard-case, a really nice selection of connection tools: Probes that have lift-off shields that are then 4mm banana jack compatible, a good set of crocodile clips and long, flexible grippers/hooks for clipping onto wires or components. With the only gripe that the USB port on the unit appears not to facilitate data transfer when using the USB port on the 'scope as the power source, this is a great little unit. For the first time buyer who doesn't need state of the art kit, this is ideal. I'm very happy with my purchase.

transazione ok

会社で２個買いました。 横河製も使用していますが、値段が１桁安く、精度の問題も起こしていません。

Only used ones so far but it works well. It is good quality probe.

Die Probe funktioniert prima, die korrekte Erfassung von Signalen bis 25 Mhz kann ich bestätigen, darüber hinaus habe ich es noch nicht eingesetzt. Die Attenuation ist okay, auch wenn mein Oszi nur bis 10 geht und ich etwas Kopfrechnen muss. Alles gut. Das Produkt kommt im kleinen Koffer und ist mit verschiedenen Messaufsätzen bestückt. Insgesamt recht hochwertig, wenn man den geringen Preis berücksichtigt. Ich nehme trotzdem meine Probemaster Messaufsätze, gegen welche die mitgelieferten freilich keine Chance haben. Falls sich jemand fragt, wozu man eine Differentialsonde überhaupt braucht. Auf YouTube mal nach "How to NOT blow up your scope" Video von Dave Jones suchen. Für Kinder und junggebliebene Forscher würde ich für den Umgang mit Oszilloskop immer eine solche Probe empfehlen. Den Magic Smoke durch Kurzschluss bekommt man auch bei geringen Spannungen in Verbindung mit hochstromfähigen Quellen (z.B. LiOn Zelle) wunderbar hin.
