diy lcr meter
Hi everyone,
I want to buy an LCR meter, I am a young SMPS engeneer and I want to test the transformer, inductor and capacitor I am using, my switcher are operating from 20K up to 1MHz. I also like to construct guitar and power amp, so I want to check the impedance of my pickups and speaker and if possible trace the impedance curve (on PC).
What kind of LCR meter do I need ?
Does it have to go from 20Hz up to 1MHz? (is the component be test at is operating frequency?)
Because the SMPS are high power, I need the LCR meter to accept bias current ?
I would like if you could suggest me some model of LCR.
What do you think of the:
LCR-8101(Instek)
PM6306 (Fluke)
1910-1920 (Quadtech)
4284A (HP)
This LCR meter must accept a discret bias current source because, I don`t have the money to buy one (which is 6000.00$ and more)
P.S. I don`t really understand how a bias current source work, does it act as a sinusoidal source ?
What is the difference between a impedance analyser and a LCR meter ?
