Figure 5-33 SEQUENCE EDIT MODE:Moving a Test Step. Wayne Kerr 3260B

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.

Advanced Operation

Figure 5-33 SEQUENCE EDIT MODE:Moving a 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 highlight the test step to be moved.

3) Press the soft key labelled Move and use the Up and Down softkeys to reposition the test step.

4) Complete the move of the test step by pressing the Ok softkey.

5.11 SEQUENCE RUN MODE.

To open SEQUENCE RUN MODE select the Menu control key followed by the

SEQUENCE RUN soft key. SEQUENCE RUN MODE will be opened with the last selected program displayed, regardless of whether it was selected in SEQUENCE RUN MODE or

SEQUENCE EDIT MODE.

5.11.1 Selecting a Program.

The required program is selected using the and navigation keys to scroll through the available programs. Pressing the LIST soft key will display a list of the available programs.

5.11.2 Program Development.

Entering code 50 via the data entry keypad will put the analyzer into single step mode so that as a program is run, each program step measurement result is displayed, together with the limits, regardless of PASS/FAIL results. Running a program in this way allows program limits and settling delays to be adjusted while the program is being developed. Code 50 must be entered after entering SEQUENCE RUN MODE and selecting a program, but before running the program. Code 51 or the next power-up resets the analyzer to repetitive mode.
