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...

When it comes to impedance measurement up to 120 MHz we think the Wayne Kerr 65120 is the best in the market - even better than the Agilent products.
www.eandiltd.com
A great successor to the old ENI amplifiers. We use E&I linear class A amplifiers for RF power and they never break.

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.
