C h a p t e r 3 | F r o m L a b E q u i p m e n t t o P o i n t o f T e s t noise management also arise, as smaller systems are more closely packed together, leading to an increased chance of interference and overheating— both of which are detrimental to measurement results. In a similar fashion, another challenge is designing a power- efficient system. Portable systems are necessarily battery powered, meaning that extending their usable battery lifetime requires designing low-power systems that consume minimal power. Lower power systems also aid in miniaturization, as they reduce the impact of thermals on the system. Reducing power consumption often necessitates a balance between performance and sensitivity. Typically, electronics operating at lower power levels exhibit increased susceptibility to noise and inaccuracies in measurement. Similarly, achieving acceptable performance in a portable form factor is a nontrivial design task. Real-world applications need fast-sampling instruments that can capture all data without missing a thing. Achieving greater performance is often at odds with achieving low power, so simultaneously achieving both is a delicate balancing act. Finally, concerns over cost always emerge. Highly sophisticated instruments— especially those with cutting- edge technologies for high performance, power efficiency, and rapid measurement— often come with a high price tag, making widespread deployment challenging. Analog Devices helps its customers overcome the challenges of in-field instrumentation by offering • A wide breadth of products that fit the needs of any instrumentation application • Highly integrated modules and solutions that minimize size and power consumption, as compared to discrete implementations • Application-focused solutions fully optimized to meet the needs of specific instrumentation use cases A common challenge is transitioning a test procedure from R&D/production to field test where the measurement may need to be the same but the qualities that are most valued in the new environment may be different."
