    PCB coil Inductance measurement

    yes tracks are very thick, around 12um 1631718590 around 40 Ohm per layer is ok, connections between layers should be ok maybe I can try with a VNA to obtain L

    PCB coil Inductance measurement

    yes they are in series copper tracks are 50um width and around 12 um thick, distance between tracks is 100 um I expected R around 10 kOhm, I have performed also a magnetic calibration of the Area, it seems there are no shorts between layers

    PCB coil Inductance measurement

    Hello everyone, I have a PCB coil ( 32 layer, each layer has 8 turns) and the outermost dimensions of the coil are 600 mm x 4.5 mm, resistance is around 11k Ohm. I would like to measure the total inductance of this coil, I tried with an LCR meter in parallel configuration but it is showing a...

    Help with KEPCO power supply used as AC amplifier

    Hi, thanks for the help. Actually I want to obtain the phase difference between the coil output voltage and the excitation current in the outer loop (coming from Kepco amplifier in current mode). For this reason I used a shunt resistor in series with the current loop (source) to obtain a...

    Help with KEPCO power supply used as AC amplifier

    HI, thanks for the help. the pick up coil is made of 150 turns, R=767 ohm, L=76 mH, it has twisted pair cables that I connect to the analog input of my DAQ as floating source

    Help with KEPCO power supply used as AC amplifier

    Hello everyone! I am trying to obtain the phase relation between the output voltage of a pick up coil (wound coil of 150 turns), when inserted into a variable magnetic field, and the filed excitation current. This field is obtained from an alternating excitation current that flows into a wire...
