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.

Set Condition

Moves the cursor, and confines it to, the bin limits area of the screen. The limits are set by highlighting each field using the navigation keys, then entering the limits with the data entry keypad. The and navigation keys move the cursor left and right one step at a time; the and navigation keys move the cursor up and down the column. See section 5.9.1 for more information about setting bin limits.

Moves the cursor, and confines it to, the test conditions area of the screen (bottom-left-corner). The test conditions are set by highlighting the parameter with the and navigation keys, then altering the setting in pre-determined steps with the and navigation keys, or by using the data entry keypad.

CALIBRATE

See section 4.3. Note: this is not a binning calibration.

Note: If the BINNING soft key is pressed when the binning option is not fitted, the analyzer will report Unit Not Available (Figure 5-22).
