Transformer tester with telecom functions

23 May 2001 Test & Measurement

The explosive growth of PCs connected to the telephone system for Internet access has resulted in a need to measure insertion loss (IL) and return loss (RL) of line matching transformers. British-based company Wayne Kerr has introduced the 3260B Precision Magnetics Analyser for just this purpose.

Distributed in South Africa by Protea Electronics' Communications & Measurement Division, the 3260B delivers top-of-the-range performance and functionality.

The user can select values for terminating resistance or impedance and configure a damped network or series blocking capacitor, if required. Complete component characterisation is also available using the analysis mode. The 3260B can graph any of the measured parameters such as inductance or impedance, including secondary term, against frequency, AC drive level or DC bias current. Up to 124 A of DC bias current can be applied. The graphed response can be displayed linearly or logarithmically.

Key features include: wide frequency range - 20Hz to 3MHz; basic accuracy - 0,1%; telecom measurement function; analysis mode (graphing); swept-frequency, AC drive level and DC bias current; comprehensive measurement functions, including leakage tests; intuitive operation; IEEE488 control using free LabVIEW driver.

The Wayne Kerr range provides a full complement of measurements, which can test a wide range of inductors and transformers. The new products 3255B, 3260B and 3265B, provide industry-leading accuracy, fast measurement speed and a full range of measurement functions.
