Copper Mountain Technologies
Measuring Impedance for Power Dist. Networks . In analog circuits, the peaks can result in increased noise density and in analog to digital converters the peaks result in spurious responses. The power rail impedance is typically controlled by the careful selection of bulk aluminum or tantalum capacitors, ceramic decoupling capacitors, inductors, and ferrite beads. The instrument of choice for these impedance measurements is a vector network analyzer and the most common and highest accuracy measurement is the 2-port shunt through technique, using...

Red Pitaya
Portable Electrical Impedance Tomography (EIT) Sampled Pattern Matching (GVSPM) algorithm and the Tikhonov (TK) regularization algorithm are used to reconstruct the image generated by the EIT system. The reconstructed images by using Red Pitaya STEMlab are compared with a commercial impedance analyzer IM3570 within frequencies of f = 100 KHz. The results show that the maximum difference of the image correlation between Red Pitaya STEMlab and IM3570 is 5.36%. Finally, the EIT system are used to image the conductivity of eggs during heating... (read more)Browse Logic Analyzers Datasheets for Red Pitaya -
