90-Degree Optical Hybrid
-
Six-port hybrid devices have been used for microwave and millimeter-wave detection systems since the mid-1990s and are a key component for coherent receivers. In principle, the six-port device consists of linear dividers and combiners interconnected in such a way that four different vectorial additions of a reference signal (LO) and the signal to be detected are obtained. The levels of the four output signals are detected by balanced receivers. By applying suitable baseband signal processing algorithms, the amplitude and phase of the unknown signal can be determined.

Single Phase Site Energy Meter Test Instrument Type KP-P1001-A
-
Bofa Instrument & Equipment Co., Ltd
Single phase site energy meter test instrument type KP-P1001-A (without voltage and current source) is an ideal instrument to test all kind single phase energy meters accuracy below 1.0, especially for meters on site. During tests, the tested meter must be on load condition (that means the tested meter must be working). The instrument tests the errors by comparing energy impulse from the tested meter with energy impulse from the reference meter inside the instrument.

ECU Calibration
-
Designing an Electronic Control Unit (ECU) is only the beginning. The features in ECUs, such as Powertrain Control Units, are quickly becoming more complex and offering more features. Thousands of variables are now provided for the engineer to modify during the in-vehicle calibration phase, and fine tuning them is as complicated as it is critical. Calibration tools significantly impact the efficiency and effectiveness of the ECU development process. These tools are typically comprised of PC-based software to perform the adjustment of the variables and an ECU hardware interface to provide the connection of the software to the controller. Teams must be able to measure and time-align relationships of inputs and outputs and make real-time modifications.

Isolation Transformers
-
Osborne’s Isolation Transformers are used to step-up, step-down and isolate voltages in single phase circuits. Isolation may be used to provide output circuit immunity from voltage spikes and noise (both common-mode and transverse-mode) present on the input system. The isolation can allow separate grounds on both the input and output sides of the transformer. Osborne also designs with a range of electrostatic shielding to provide several levels of noise immunity.

Safety
-
Chroma Systems Solutions, Inc.
The purpose of safety testing medical electronic equipment is to be sure that a device is safe from electrical hazards to the patient and caregivers. There are a number of UL, European and Canadian standards that serve as the ruling body on how medical products will be tested, one in particular, IEC60601 (the International Electrical Safety Standard for medical electronic equipment) is experiencing “global harmonization,” meaning it has been accepted and implemented around the world. The IEC60601 standard is mainly intended for product development where safety considerations must be taken into account early in the design phase of a product, however much of it is applied to production line testing since it is the only way for a manufacturer to be sure they are shipping safe product.
