The Electronics Lab and Machine Shop

    The Electronics Laboratory is located in the basement of the 
Neurological Institute at 710 W. 168th Street in room B04A. It 
supports an MR Imaging Facility of two 1.5T magnets, a 3T magnet, a 
vertical bore 9.4T animal system, and the community at the Columbia 
University Medical Center. 
    Test equipment required for any analog or digital application is
available. Spectrum, Network, and Impedance analysers on a GPIB to 
USB bus can be controlled from a pc, most commonly thru Labview interfaces.
A logic analyser and digital oscilliscope are also on this bus.
    Orcad schematic design and pc board layout tools are used. Most of
the rf circuits needed can be approximated using spice simulations.
    A large stock of rf devices, prototype components, and light fabrication 
materials are located here. Some applications require highly nonmagnetic
components, connections, and shielding.
 

    Accompanying the above facility is a machine shop in rm B04G. It is 
equipped with standard machining tools, stock, and hardware. Welding and
aluminum anodization are available off site.
