Oct 31, 2016 · There are low frequency "VNA" with low source and high load impedance (often called T/R ports) that work at lower frequencies. The E5061B is one example which is a unit that offer both 50Ohm s-parameters to 3GHz as well low frequency operation to just a few Hz. It also has a dedicated low frequency port with a low/high impedance interface.

Three different methods can be applied to accurately measure passive components with a vector network analyzer.

7 May 2021 ... I got a N2PK VNA, but I don't do any RF, it was just for audio :D (although one could argue that 50MHz clocks are not really "low frequency")Precision mmWave measurements normally require a VNA with built-in capability or mmWave extenders to augment the frequency range. But did you know it’s also…The result is frequency response ripple. The magnitude of the ripple will depend upon the severity of the impedance mismatch at the interface, and the period of the ripple over frequency will depend upon the length of the cable. Ripple can appear in a measurement of S21 even if the frequency response of the DUT is perfectly flat.RF traces on PCB. SMA connector on right, matching components and input to power detector IC.
