Here's a low cost project SDR VNA antenna analyzer - not RTLSDR AFAICT.The impedance adapter uses a resistor bridge to extend the dynamic range. The impedance adapter, shown connected to the VNA in Figure 5, has a recommended range of 20mΩ at 1Hz. At the resonance frequency of 20MHz, the recommended minimum impedance measurement is about 6Ω. At low frequency, the maximum recommended impedance is 600kΩ.Feb 23, 2022 · 12. Spectrum analysers are often specified down to 9 kHz because this is the lowest frequency of conducted or radiated emissions that is specified in the Electromagnetic Compatibility (EMC) standards. These standards apply to most electronic devices. They regulate both the strength and frequency of intentional emissions like WiFi, but also the ... The lower frequency IF signal has less insertion loss from the cable run to the VNA. For long distances, this will significantly reduce the in-sertion loss: the same cable with 4 dB/m loss at 40 GHz may only have 1 dB/m loss at 4 GHz. While this approach reduces the loss of the received signal from the VNA, the cable carrying the LO sig-1.

It sends out RF signals at some frequency and analyzes the reflections. A tuneable oscillator is fed into a mixer with the incoming reflections. This down-converts the reflections from their RF frequency to a fixed IF. The VNA Output (TX) is connected to the output PDN through a direct connection. The VNA Input (RX) is connected to the output of the PDN through a semi-floating differential amplifier on the VNA RX side. Residual impedance will directly affect very low impedance measurements.
