Automated test systems rely on the performance, quality, and configuration of the signal switching that they are based on, yet the most significant challenge when considering switching for automated test systems may not be technical at all. Often we hear from customers that they feel switching is the last portion of their test integration strategy that needs to be considered. Switching is so simple, maybe even boring… how can anyone go wrong?

Think about the questions you should ask yourself surrounding switching for automated test systems such as:

  • What is a the importance of high-quality switching?
  • What are the differences between reed relays, electromechanical relays and solid-state relays?
  • What types of switching configurations are available?
  • Which cables, connectors and mass interconnect products should be included with my switch module?

The switching system is intrinsic to the success of the test process, so it’s important to understand the possibilities and limitations. However dull switching may seem, there are very many challenges to be considered, but the information is all here to help you.

Understanding Programmable Resistors for Sensor Simulation in Test

If you think about it, sensors control much of our daily lives. Sensors ensure that the food in your refrigerator stays cold, programmable-resistors-image-for-whitepaper-lpcount your steps on a smartphone, and even protects you in an automobile accident. So many devices in our personal lives as well as in business and other markets contain sensors.

All these sensors add a layer of complexity to your test strategy, as you need to simulate them when testing the circuit board that makes decisions based on a sensor’s response. Since it is usually not practical to incorporate actual sensors into a test fixture, Pickering Interfaces has created external hardware that is designed to replace these sensors in a test program. In this paper, we will talk about sensor simulation and how to select these products. With Pickering’s history of more than 15 years designing programmable resistors, we have the expertise and product depth to play an important role in testing sensor-driven products.

Learn the right questions to ask when testing sensor-driven products.

  • What is a programmable resistor and why is it used for sensor simulation in test?
  • What are the different types and parameters for programmable resistors?
  • What if I need more accuracy in my test?
  • Are there different types of configurations I can use?

As you can see, there are many things to consider when selecting programmable resistor modules in test. It is undeniable that sensors are in virtually every application for electronics, making testing important, and sensor simulation can help you get there. We recommend you take a look at our latest whitepaper -
