The implemented VNA operates in the frequency range between 30 MHz and 850 MHz with an accuracy comparable to a benchtop instrument. Accurate measurements in this frequency range are relevant in several applications. Many possible options and tradeoffs should be considered before selecting an RF switch matrix, which comes in three flavors: blocking, non-blocking, and super non-blocking.Time domain low pass impulse In low-pass mode, you can simulate TDR. In low-pass mode, the start frequency must be set to 50 kHz, and the stop frequency must be set according to the distance to be measured. The trace format can be set to REAL. Examples of Impulse response in open state and impulse response in short state are shown below.
