High Performance Analog & Mixed Signal Test Solutions
Applicos
-
Effective mixed-signal test solutions demand know-how and experience. Low level analog signals need to be stimulated and analyzed near fast switching digital logic. Cross talk, magnetic fields, clock jitter, ground noise and non-linearity of components, are just a few of the problems that must be addressed. Applicos knows what it takes to design and produce high quality mixed-signal test solutions. They have been servicing the mixed-signal test industry since 1993 and have established a distinguished reputation for providing our customers with high performance, cost effective solutions.

Scanning Magnetic Microscope
Circuit ScanTM 1000
-
Operating circuits within a semiconductor generate external magnetic fields near the surface of the device. These magnetic fields, while weak in strength, contain information about the spatial variation of current density flowing within the circuit. Micro Magnetics has developed the CS1000 to make practical use of this information and provide engineers with valuable information about what is going on inside circuitry non-destructively.

4 Port Devices
-
Four port devices can be realized by joining two 3 port devices via the appropriate ports. As system performance requirements become more demanding, new design approaches must be adopted. These include Faraday rotation devices and phase shift circulators. The bandwidth and isolation limitations of 3 port devices are overcome through a distributed architecture that enables more ferrite material to be incorporated into the transmission path, thereby achieving an increase in the biasing magnetic field. Phase shift circulators can be designed to handle higher RF power than 3-port devices.

Solid State NMR
-
Magnets for NMR experiments are required to have a high homogeneity, which can be maintained over a wide range of field. Experiments are performed at fixed frequency and the spectrum is obtained by sweeping the magnetic field. This requires the field to be stable in spatial homogeneity and change steadily and repeatedly over time.
