The Wayne Kerr 3255B Inductance Analyzer 500 kHz is able to accurately characterize devices in a clear and simple manner with comprehensive parametric tests. Using the parallel Centronics interface the user can directly print all test results for further analysis and archiving. This instrument can also be controlled from a PC and results can be read back for analysis and storage via the optional GPIB interface. At the design stage of component development it is very important to analyze 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 125 A.
