The 3255B range of inductance analyzers are able to accurately characterise devices in a clear and simple manner. The inductance analyzers are available in three versions 3255BL (200 kHz), 3255B (500 kHz) and 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, AC drive levels or DC bias currents.

The AC drive level can be set between 1 mV and 10 V. DC bias current can be set from 1 mA to 1 A internally (optional). Using the external 3265B range of DC Bias Units bias currents can be set to a maximum of 25 A.

Printed output of test results
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.
