Measuring resonant frequency and bandwidth for a 2mH coil
Hello Gunnar and Electricpete, Thank you for input, very good idea using transient response than frequency responce. I will try with the system I have today and prezented in first post, and then with the ideea from you and compare results. The most important will be accuracy of measurement...- MishuRF

Measuring resonant frequency and bandwidth for a 2mH coil
Hello all, I have one question related with measuring ferrite coils, unknown values(in the area of 1mH to 4 mH). I need the resonant frequency (arround 125kHz) with les than 1KHz accuracy. There is an ideea of creating a field with a signal generator(sweep freq @ 125KHz) and a known coil...- MishuRF

how to measure UHF RFID antenna port impedance
Hello, In what range of frequency works your RF ID antenna? Is the setup used by you calibrated somehow? Is there any offsets taken in consideration? Maybe a picture would be very helpful for us ,like zappedagain said in the above post. Mishu- MishuRF
