Considering a general scenario that prevails globally, there is hardly any car which is driven without entertainment being an inherent part of it. At least there is music if not anything else. Since there is an increasing importance of in-car entertainment, automotive electronics is becoming more and more complex. In order to ensure the smooth functioning of this, electromagnetic interference (EMI)/electromagnetic compatibility (EMC) testing holds utmost importance. Importance of the testing The requirement of electronics in automotive does not end at the entertainment part only. Automotive electronics is critical for its use in all forms of communication and safety related requirements in vehicles these days. EMI/EMC test equipments play…show more content…
This has been done in order to provide improved reliability and safety for users of electrical and electronic equipments in their vehicles. In an attempt to ensure compliance with these regulations, most automotive companies these days employ the services of a specialised test facility to perform the actual compliance tests required for EMI certification. The test facility might belong to an outside company (a “test house”) or to an in-house EMC department. A lot of effort is made towards designing the test equipments good enough to minimise as much EMI signatures as possible. Naresh Narasimhan, country marketing manager, Tektronix India says, “Most engineers employ good design practices to minimise the potential for EMI problems. It is common today to perform pre-compliance measurements during the design and prototyping stages to identify and address potential EMI issues before the product is sent out for compliance testing. These techniques reduce the risk that the product will fail the final full compliance at the test…show more content…
To help users diagnose noncompliant signals, the receiver should include a variety of built-in mandatory diagnostic resolution bandwidths, range of detectors and multi-trace displays. It should have diagnostic tools like Amplitude Probability Distribution (APD), Time Domain Scans, marker functions, trace zoom, zone span, spectrograms and Keysight exclusive Strip Chart. To enhance instrument longevity, upgradeable options include CPU, memory, disk drives and I/O ports. What tasks will you do? Without asking this basic question, you could end up with tools that have the wrong features or improper ranges for the tasks at hand. What environment will you work in? Do you work in lab or in the field? Will your equipment need to be heavy duty, waterproof, and rugged? Or will you mainly perform delicate, precise measurements
