The Wayne Kerr 3260B is a Precision Magnetics Analyzer that allows for the 2-terminal and 4-terminal (Kelvin) measurement of inductors and transformers. It also offers DC resistance measurement capabilities. The frequency range for the device spans 20Hz to 3MHz, and the drive level can be adjusted between 1mV and 10V rms. The analyzer supports ALC to maintain drive level at the component. In addition, the 3260B has a DC bias current adjustable between 1mA and 1A and provides the option to use external 3265B DC Bias Units to achieve up to 125A DC bias current.
