Before performing the measurement, a Thru calibration of the VNA is required to avoid additional series resistor and impedance mismatches. At high frequency, mismatches commonly appear. The use of a SMA connector is favored to eliminate mismatch errors.Precision millimeter-wave (mmWave) measurements normally require a VNA with built-in capability or mmWave extenders to augment the frequency range. This equipment may be used to evaluate mmWave mixers which are commonly used to up-convert or down-convert 5G signals back and forth from baseband frequencies.Maybe consider scoring an old HP 3563A off ebay. They tend to go for $400 to $600 and cover DC to around 100kHz; that's more than enough span for characterizing audio circuits and note that the 3563A measures both phase and frequency response (ie - it is a proper vector network analyzer, just limited in frequency range).This device contains a lot of test components that you can experiment with while exploring the functions of your Nano VNA. Note the 30 MHz low-pass filter (LPF ) and the 100 MHz high-pass (HPF) filters in the upper left. Today we start our investigation of common filters found in all amateur radio equipment, specifically low-pass and high-pass ...VLF é a sigla para Very Low Fequency - Frequências Ultra Baixas.

A new VNA architecture provides better test data and more accurate information to improve and refine device models. The ability to combine stable, accurate high frequency and low frequency S-parameter data in a single frequency sweep eliminates the need for data concatenation and its associated errors.

Figure 1. Periodic impulse response in time domain using a VNA with IDFT. Signal integrity engineers can select two types of time domain when using a VNA: Low Pass Time Domain – The VNA can simulate a TDR with a step stimulus with this option. An impulse stimulus can also be applied, so engineers can view impulse responses in the time domain.
