From 10KHz to 1MHz, the home made transformer has higher common mode attenuation than the PICO. Adding one or two more turns would certainly help the low frequency performance but it hurts the insertion loss. WebMar 18, 2014 · Many engineers are just starting to perform PDN measurement. Typically, these measurements are performed using a vector network analyzer (VNA). A 1-port measurement can be used for impedance levels above a few hundred mΩ. A 2-port shunt-thru measurement is used for applications as low as 1mΩ and in some cases even lower.
