New Micsig Current Probe CP503 | Voltlog #443

High quality PCB Services https://pcbway.com Join me in this video where we take a closer look at the new Micsig CP503 current probe. It is a different form factor than the previously reviewed CP2100A but the real changes are under the hood. Once again Micsig brings to market a current probe which is affordable but has features and specs that you only find in multi thousand dollar test gear

#Micsig #CP503 #CurrentProbe

Welcome to a new Voltlog, I’ve been a happy user of Micsig test gear for the past couple of years, my first product was the CP2100A current probe andat that time it was really the best current probe in this affordable price range and it could even outperform much more expensive alternatives. I did a review of it in Voltlog #330.

As explained in that video a current probe is not something that everyone needs, certainly not required for the average hobby projects, it’s more of a special tool that is used whenever you need to take a look at the current waveform in a high speed isolated manner. That could mean looking at the current waveforms for various parts of a switch mode power supply circuit AC or DC, power factor correction or for the current waveform at the input of a particular load, measuring inrush currents or like in automotive you would want to look at the waveform when driving an fuel injector coil. You wouldn’t use something like this for measuring the power usage of your low power microcontroller because you would be in the noise level of what this instrument can do.

So that was a short introduction and I also have to mention that back then the Micsig CP2100A and the other variant CP2100B were considered high bandwidth probes at 800KHz and 2.5MHz respectively. Well Micsig recently released a newer model the CP503 which I have here for review. This unit has been provided by Micsig through their EU distributor ELESHOP which I highly recommend you checkout if you are looking to order one of these in the EU, a link will be provided in the description below.

And this model can go up to 50MHz and 100MHz depending on the variant you choose.Additionally they also have two connection methods or variants of this probe, you could have the standard, universal BNC connection which would work for any oscilloscope input but now you can also have the UPI interface which is supported on their newer Osciloscope like the STO1004 which I reviewed in Voltlog #438.

The advantage of having the UPI interface is that there are additional data and power pins, besides the BNC signal connection. This means you can have active circuitry built into your probe, calibration data, the scope can talk to the probe, read that data and decide how to adjust scope parameters based on that. So in my case I have the UPI interface version but you can also get it as a standard BNC interface which will work with any oscilloscope.

As we notice the CP503 has a totally different form factor, I like both of these form factors, I haven’t seen any limitation with either but I’m sure that this thinner one would work better for when you need to probe within some tight spaces. I have the CP503 model here which is rated for 50MHz, while the CP1003 is rated for 100MHz. But the differences between the two models pretty much stop at bandwidth which is huge BTW, I mean any kind of power supply system you might be working on, this will got you covered.
