data sheet
3255b and 3255bq are highly versatile and accurate inductance analyzers able to characterise devices in a clear and simple manner. the three  models in the range are the 3255bl (200khz),3255b (500 khz) and the 3255bq (1 mhz).
at the design stage of component development it is very important to analyse how components performs under different operating conditions. this includes operation over a range of frequencies, acdrive levels or dc bias currents.
the ac drive level can be set between 1 mv to 10 v. dc bias current can be set from 1 ma to 1 a internally (optional) with external dc bias units available increasing the maximum current to 125 a(3255b and 3255bq).

printed output of test resultsusing 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 upon request or may be downloaded from thiswebsite providing a base from which a user can develop a specific test application.
bin sortthe 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.
component tests with up to 125 a dc bias current
3265b/25a dc bias unit can deliver up to 25 a of dc bias current in steps of 0.025 a
the 3255b and 3255bq enable components to be measured at up to 125 a when multiple external 3265b/25a dc bias units are used. extended dc bias capability is also available with the3255bl which uses the 3265b/5a or 3265b/10a to extend the dc bias current available to 50a.
up to five of the dc bias units can be used in parallel to give a wide range of dc bias currents.
the 3255b inductance analyzer can optionally 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 users against back emfs. it is also fully protected against over temperature, excess voltagedrop and sense lead failure.
smd inductor tests up to 50 a
1009 dc bias fixture enables currents up to 50 a to be applied to an smd inductor
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 theoperational bias currents. the fixture operates with either one or two 3265b/25a wayne kerr dc bias units and a 3255b inductance analyzer. if two 3265b/25as are used then the optional5-328-2005 high current lead set will be required.
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 acustom carrier design service is available.
stable component fixturing ensures high accuracy and repeatable measurements. enclosed fixtures, with safety interlocks, minimises risk to operators.
