Multi-tap Transformer Measurement Using a Scanner and a LCR Meter
Show Description
Introduction
With the progress of recent electronics equipment and digital networks, production amounts are increasing of the transformers which contribute to equipment miniaturization, low power dissipation and higher quality. Therefore, improvement of select estimate efficiency is required at the production line or incoming inspection. Noticed recently, improvement of estimation efficiency is required for pulse transformers which are used in LAN or ISDN digital networks, and for multi.-tap transformers with three or more pole taps, such as switching power transformers. This application note shows an effective multi-tap transformer measurement using a scanner and the 4263B LCR meter.
