Comparing physical layer CAN diagnostic devices
You have problems with your bus, in your system or at your customer’s site. You have to measure and stop guessing – what you need at this point is a diagnostic device.
The market is confusing, they try to deceive with false promises but giving no real comparison. We try it and compare the GEMAC devices. For this comparison, we take the three devices that do measure at the physical layer. CANalarm has special features, which has nothing to do with physics and CANvision is as protocol monitor working on logical layer only. Therefore these two products are not listed in this comparison.
A table like this with features can only be some kind of hint. Features differ from device to device, even when both of them have it. There may be a different understanding of a feature or a different expectation. Please open a ticket within the support area if there are special questions running in your mind.
In this article, we go even deeper into the agony of choice and make recommendations.
