At the design stage of component development it is vitally important to understand how the component performs under different operating conditions. This might include operation at diverse frequencies, AC drive levels or DC bias currents.
The 3260B Precision Magnetics Analyzer can plot any of the measurement functions, such as inductance (L) or impedance (Z), (including secondary term) against frequency, AC drive level or DC bias current.
Frequency sweeps within the range 20 Hz to 3 MHz can be selected. There is a choice of either linear or logarithmic frequency displays.
3260B is especially suitable for measuring parameters on telecom transformers.
The selected parameter and its secondary value are presented graphically. AC drive levels can be set between 1 mV and 10 V. DC bias current can be set from 1 mA to 1 A internally. Using external 3265B 25 A DC Bias Units bias currents can be set to a maximum of 125 A.
With the dramatic growth of PCs connected to the telephone system for Internet access has come the requirement to measure Insertion Loss (IL) and Return Loss (RL) of line matching transformers.
The 3260B Precision Magnetics Analyzer not only measures IL and RL but the instrument also allows the user to enter the values for terminating resistance or impedance, if complex, and to select a damped network or blocking capacitor if required.
Using the parallel Centronics interface the user can directly print all test results for further analysis and archiving.
In addition, via the optional GPIB interface, the instrument can be controlled from a PC and results can be read back for analysis and storage.
LabVIEW™ drivers are available on request or can be downloaded from the web site, www.waynekerrtest.com, providing a base from which a user can develop a specific test application.
The binning function allows component manufacturers to sort components in up to ten bins. Sorting is carried out either by absolute values or by percentage of values.
To evaluate components at high currents up to 125 A the optional 3265B DC Bias Unit is used.
25 A of DC bias current can be set in steps of 0.025 A with one unit whilst up to five units can be used in parallel to give up to 125 A DC bias current. The standard 3260B Precision Magnetics Analyzer can provide an internal DC bias from 1 mA to 1 A.
The 3265B has a number of safety and protection features including a safety interlock system to protect the user against back EMFs. It is also fully protected against over temperature, excess voltage drop and sense lead failure.
With the addition of the 1009 DC Bias Fixture DC bias currents up to 50 A can be applied to an SMD inductor during component test in order to evaluate the devices thoroughly at the operational bias currents.
The fixture operates with one or two 3265B Wayne Kerr DC bias units and a 3260B Precision Magnetics Analyzer.
Four rear panel mounted BNC connectors and two captive high current cables ensure simplicity and ease of use with the 3265B.
Interchangeable component test carriers ensure that the 1009 DC Bias Fixture may be used with a wide variety of devices. If a device package is not supported by one of the standard carriers then a custom carrier design service is available.
Stable component fixturing ensures high accuracy and repeatable measurements. Enclosed fixtures, with safety interlocks, minimises risk to operators.
