SAR Testing for Survey Equipment: What You Need to Know

SAR Testing for Survey Equipment: What You Need to Know

The importance of safety and compliance for devices like cell phones, laptops, and tablets is often discussed, but wireless survey equipment must also comply with SAR standards. In this article, we’re diving into the intricacies of SAR testing for survey equipment, shedding light on the unique requirements and considerations that govern this crucial compliance process. We’re here to help answer questions for survey equipment manufacturers. Join us as we navigate through the intricacies of SAR testing, unveiling the essential elements that shape compliance and safety in the realm of surveying technology.  

Why SAR Testing is Necessary

SAR testing, or Specific Absorption Rate testing, is crucial to ensure the safety of users and operators in relation to radiofrequency (RF) emissions of wireless devices. Surveying equipment often incorporates wireless communication capabilities, and SAR testing is essential to evaluate the potential absorption of RF energy by the human body during operation for a variety of reasons.

These reasons include safeguarding human health, ensuring regulatory compliance, and accounting for the unique operating environments and technical specifications inherent in the field of surveying technology. By undergoing SAR testing, manufacturers can demonstrate their commitment to user safety and adherence to established standards in the deployment of wireless capabilities in surveying equipment.

How Survey Equipment Uses RF Energy

Survey equipment utilizes RF emissions primarily for wireless communication, data transmission, and, in some cases, positioning and geospatial applications. The integration of RF technology enhances the functionality and efficiency of surveying instruments, allowing for real-time data collection, collaboration, and increased mobility.

For instance, land surveying instruments equipped with wireless capabilities can transmit measurement data directly to central systems or computing devices, eliminating the need for cumbersome physical connections. This wireless communication streamlines the surveying workflow. 

In addition, RF emissions in survey equipment often support features like remote monitoring and control. GPS-enabled survey equipment, in particular, relies on RF emissions for precise location-based services, contributing to accurate geospatial data collection. 

Overall, the integration of RF emissions in survey equipment enhances mobility, flexibility, and real-time data access, revolutionizing traditional surveying practices.

Requirements for SAR Testing of Survey Equipment

Regulatory standards governing Specific Absorption Rate (SAR) testing are established to ensure that the radiofrequency (RF) exposure levels of wireless devices do not pose a threat to users. The International Commission on Non-Ionizing Radiation Protection (ICNIRP) and the Federal Communications Commission (FCC) in the United States are key organizations that have set guidelines to protect individuals from excessive RF exposure. The standards typically specify permissible SAR levels, taking into account factors such as frequency, power density, and exposure durations. Manufacturers are required to conduct SAR testing on their devices and ensure compliance with these standards before bringing products to market. 

Non-compliance may lead to regulatory hurdles, product recalls, or legal consequences, emphasizing the importance of adhering to SAR regulatory standards.

Challenges in Testing

There are some challenges in SAR testing for survey equipment that can complicate the process, underlining the importance of working with SAR and RF exposure experts. 

Because of its purpose, survey equipment tends to incorporate a variety of different technologies in one device, such as GPS and wireless communication protocols. Compliance testing needs to address the impact of these technologies on RF emissions.

Survey equipment is also typically operated for an extended time, particularly during field surveys. To show compliance, testing needs to consider the long period of exposure when these devices are in use.

Further, survey equipment often operates in a variety of frequency bands. Testing needs to comprehensively cover these frequency bands to ensure that the assessments align with regulatory standards and guidelines.
