Heat Flux Sensors
MF Series
-
EKO Heat Flow Sensors are applied to measure the heat flow or thermal conductivity in materials and radiative IR flux emitted by body surfaces. The sensors are suitable for indoors applications, some models made for outdoors purposes and are available in different sizes and thickness. All sensors are extremely flat, which is a big advantage considering the minimum interference with the conditions of the testing area the thermal dynamics. Since sensor foils are relatively flexible those can easy be applied on curved surfaces and can be used in different applications to measure the performance of insulating materials in refrigerators, container walls, pipes, building constructions, etc.

General Purpose Heat Flow Meters
-
Thermal conductivity defines a material’s ability to transfer heat. A precise and accurate measurement is critical for any process or material experiencing large or fast temperature gradients, or for which the tolerance for temperature changes is exacting. Accurate values are essential for modeling and managing heat, whether the component of interest is called on to insulate, conduct, or simply withstand temperature changes. Information about these properties are routinely used in heat transfer models of all complexities. Thermophysical property measurements also reflect important information about material composition, purity and structure, as well as secondary performance characteristics such as tolerance to thermal shock.

Optical Receiver Stress Test Solution
N4917B
-
The N4917B software provides an automated standard compliant stressed receiver sensitivity test according to 100GBASE-LR4, ER4 and SR4 test specification. In order to do this kind of test, several test instruments such as a bit error ratio tester, digital sampling oscilloscope, optical reference transmitter and tunable laser source are required to operate together to achieve a compliant, repeatable optical stressed eye. This stressed eye is then fed to the receiver under test, where bit error ratio is measured under the stress conditions as defined in the standard.

Load Testing vs. Stress Testing
-
A load test is a planned test to perform a specified number of requests to a system in order to test the functionality of the system under specific levels of simultaneous requests. A load test ensures that a web system is capable of handling an expected volume of traffic, and therefore is sometimes referred to as volume testing. The goal of a load test is to prove that a system can handle the expected volume with minimal to acceptable performance degradation. The threshold of acceptable performance degradation must be defined by the testers as some value considered acceptable to the end user so that users will not bounce from the site.
