Power Inductor Testing Under Bias

The Picotest J2131A, along with your Tektronix oscilloscope, supports power inductor testing under Bias. Together they enable accurate shunt-through inductance measurement of power inductors at various bias levels - up to and including saturation currents up to 125ADC. The bundle enables the 2-port shunt through measurement using the scope’s FRA features *

Applications and Benefits

• High current DC Bias Source for measuring inductors
• DC Bias Source is 0-125Amps (from a 5A power supply input)
• Uses the 2-port shunt- through measurement to compute value over frequency and DC bias
• Multiple levels of protection for inductor disconnects
• Measure inductors from nH to 1uH

Picotest Inductor Tester Solution Bundle Add to Cart

Bundle includes:

• J2131A DC Bias Source with two (2) inductor mounts
• P9610A Power Supply
• J2113A Differential Amp
• Three (3) PDN Cables (Two (2) 0.5m BNC-SMA cables and One (1) 0.25m BNC-BNC cable)

Required from Tektronix

• Tektronix MSO4/5/6 scope with Software option 4-pwr, 5-pwr, or 6-pwr

The J2131A unit uses the 2-port shunt through test configuration to perform the inductor measurement. It cannot perform the measurement by itself. The 2-port shunt through measurement REQUIRES a ground loop breaker, such as the Picotest J2113A.
