  Makers of the very clever FE software we use. It is astonishing what can be done with this software.
• www.agilent.com
  Our preferred supplier of oscilloscopes and test equipment. We particularly like oscilloscopes that allow us to perform signal processing of signals: averaging, filtering, FFT etc...
• www.waynekerrtest.com
  When it comes to impedance measurement up to 120 MHz we think the Wayne Kerr 65120 is the best in the market.

  A great successor to the old ENI amplifiers. We use E&I linear class A amplifiers for RF power and they never break - correction: they seldom break. The one time we had a failure we contacted E&I and their service manager explained how we could fix the problem ourselves. He was incredibly helpful. I was most impressed!

  Even though we have burnt-out 2 of them we still recommend Yamaha for audio amplifiers that can be used into the near ultrasonic up to 50 kHz. Interested in a NAD amplifier that goes up to 100 kHz at 100 W.

  Impressive selection of audio and ultrasonic loudspeakers from B&W. The R&D done in support of the products is impressive too. One of the few loudspeaker manufacturers (possibly the only one) to list full specifications of product performance, for example: bandwidth (50 kHz in many cases) and harmonic distortion. We have bougth some to use in experiments in our laboratory and they sound good too!
