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.

Figure 5-31 SEQUENCE EDIT MODE:Additional Test Step

1) Open the program to be edited. See section 5.10.1.2 Loading an Existing Program.

2) Use the and navigation keys to select the insertion point of the new test step in the test program. The new step will be added to the program after the highlighted test step.

3) Press the Add soft key to list the available tests

4) Use the and navigation keys to highlight the type of test to be added.

5) Pressing the Ok soft key adds the test step to the program.

Notes:

• New primary winding test steps are always added after the last primary winding test in the list.

• New secondary winding test steps are always added after the last secondary winding test.

• New test steps mimic the settings of the step which was highlighted when the new step was added.
