A Guide to Highly Required Automated Testing Equipment

Must read

The electronics testing equipment market is booming with never before pace because of the intense market competition. People don’t only want their smartphones smart but expect the same from every electronic device. Smart light bulbs, speakers and refrigerators are some examples that have already occupied space in our lifestyle. In order to improve the intelligence of smart sensing and automation systems, automated testing equipment plays a crucial role. Basic testing devices like ohmmeter, voltmeter and ammeter still have a market but testing at a substantial level requires highly efficient automation. It is possible with some advanced equipment that we will introduce below.

List of Popular ATE Equipment 

1) Impedance Analyzer

An impedance analyzer is automated test equipment that can determine how a material or electrode surface reacts to a voltage that is continuously raised and decreased within predetermined limits. An impedance analyzer has the major advantage of allowing the user to do tests without destroying the object. This allows a producer to test any one of his items without really using or destroying them before they leave the facility. The most common applications of impedance analyzer are:- 

  • The resilience of paint coating 
  • The resilience of concrete walls 
  • Particular DNA cell measurement

    2) Oscilloscope

An oscilloscope is a tool that displays a waveform of electrical impulses and allows you to examine how voltage varies over time. A multimeter is an instrument that is utilized to measure a particular value for the voltage in circuits with consistent voltages. When you begin building more complex circuits, this becomes redundant. An oscilloscope can very handy in this situation.

You may use an oscilloscope to see how voltage varies over time. Signals are voltages that are used to transport information, such as audio that plays music on loudspeakers. An oscilloscope terminology involves four important factors i.e. 

  • Bandwidth 
  • Sample Rate 
  • Rise Time 
  • Waveform Capture Rate

    3) Digital Multimeter

A digital multimeter is a tool that can measure voltage, current, and resistance among other things. Measured data are displayed on a digital screen, making them accessible to even inexperienced users.

Some digital multimeters choose the measurement range for you automatically, so you don’t have to. As a result, even for beginners, these instruments are rather simple to operate. Testers use two types of digital multimeters for industrial use:- 

  • Handheld Models 
  • Benchtop models

As their names are illustrating, the handheld device is required for mobility whereas the benchtop comes in handy in production lines where high speed and high precision are the primary expectations.

4) LCR Meter

They include a discrete centre channel, LCR systems have become increasingly common in live installed sound. They further provide accurate panning controls all across the stereo field. Each channel in a standard stereo setup can be shifted between both left and right sides.

The LCR system includes a dedicated centre loudspeaker the centre, which makes it much more precise and easy to locate. However, in order to get the most of the LCR system, you’ll need a highly efficient digital mixer that really can take advantage of all of its features.

ATE has evolved a lot if you compare its significance and efficiency with a decade ago industry. Tools like CMOS image sensor test systems and 5G testers are transforming the electronics industry aggressively.
