GPIB control with LabVIEW driver
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, AC drive 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 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 upon request or may be downloaded from this website providing a base from which a user can develop a specific test application.
Bin sort
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.
