Testing of communication transformers with PSM units from N4L

The PSM units from N4L are very suitable for testing transformers manually or automatically (using a PC). They have the measurement capacity (DFT and true rms, from 10mHz to 2.4MHz) to perform the most commonly required transformer tests:

• Turns Ratio
• Primary inductance and resistance
• Leakage inductance
• Interwinding capacitance
• Magnetising current
• Insertion loss
• Return loss
• Harmonics
• THD
• Longitudinal Balance

Most tests require a simple circuit, such as resistors to be mounted in a test rig. Above mentioned tests can be found in the application note. For more information click on view application note.
