The final task (and the least exciting) is to document how the design works. To put the cost of the learning curve into perspective, assume that the annual cost of salary, benefits and tool costs for an engineer runs at $110k. Our experience at Algotronix is that customers are actively working within a day on plain vanilla” cores, but we also offer a safety net for more demanding designs with consultancy options. Better still, customers can sign up to get a free-of-charge evaluation copy to convince them that it is the right core.

Both antennas and their feeder cables are prone to damage. This is particularly true if any part of the system is located outdoors. Fault finding these systems can be more difficult than say testing a DC system like an electric door bell. This is because the loss of the cable varies with frequency. It may be perfectly connected when tested with an ohmmeter, but still show a high loss when transmitting power at a frequency of Gigahertz or two. Measurement of the match of the antenna and the cable loss are part of the answer. This article explains what is involved in making measurements with a dual directional coupler, and what else to look out for.

To compare the clamping performance of each device, we will take an oscilloscope screenshot of the voltage waveforms during an ESD event. We will do a side by side test keeping all the testing conditions the same. Figure 3 below shows the response of each diode on the same graph for a positive and negative ESD pulse. The input pulse used was a standard IEC61000-4-2 level 4 contact (8 kV).
