    Spitzenberger & Spies is one of the leading manufacturers of analog high performance amplifiers for industrial measurement and test systems.
    For 50 years Spitzenberger & Spies has gained extensive experience in fully compliant test solutions for the following applications



    Based on our 4-quadrant linear power amplifiers we are able to simulate all supply voltages from DC to several hundred kHz with power up to the megawatt range.
    Our products are mainly used in development and test laboratories and quality assurance departments.
    Also many certified bodies all around the world rely on Spitzenberger & Spies.


    We are not only a manufacturer; we are a well experienced Solution Partner to our Customers.
    The customer knows his problem – we know how to solve this by using our modules and setting up an individual solution which really fits and helps the customer to get (technically and economical) the best result.
    Across the board we have long term relationships (20 years and more) to our customers, and it is not uncommon to see our products in 24/7 use for 10 years and more.


    More and more internal and external electronic devices are used inside cars and aircrafts.
    All devices are connected to the power bus (i.e. consumer electronics by USB or cigarette lighter). And all devices can interact by sending feedbacks into the power bus. Just think about the light in your car when your battery is low and you turn the starter…
    But even more than this, internal devices with switch mode power supplies may be a heavy challenge for the safe operation of other vital equipment in a vehicle, like navigation or communication devices.


    Therefore simulating and testing in the field of EMC (Electro Magnetic Compatibility) against Immunity and Emission limits gets more and more important.


    We deliver German engineered craftsmanship with experience since 50 Years!
    Most of our amplifiers are based on linear technology. This gives us the advantage of shortest rise times and highest precision and fastest readjusting.
    Our amplifiers can supply every imaginable load.
    Our products are highest quality and have a very long lifetime.
    We offer quick support and help to all our customers worldwide.

    Your prototype is safe in our hands

    Sometimes a car or any other prototype is being “De-Tested”.
    I.e. the test-equipment did send too much power to the EUT so that this did catch fire!
    Some of our new customers did have this issue and did switch to Spitzenberger & Spies because with our experience of decades we developed special electronic inside our equipment to protect the devices under test!
    Imagine what amount of money is in response when a prototype is under test. – Therefore take an experienced and reliable test-system.


    Just a short time ago a very famous German test lab was claimed compensation because of violating control and supervisory duties.
    Do not use any pre-compliance test systems. Take reliable equipment from a manufacturer with deep background knowledge and high skilled engineers who are working hand in hand with the committees (e.g. IEC).
