RF TEST CABLE (RF test cable) how to test the impedance?

1、Tested by TDR method, instantaneous domain reflection.

2, Time Domain Reflectometry TDR (Time-DomainReflectometry) technique. The technique involves generating a time-step voltage that propagates along the transmission line. Using an oscilloscope to detect the reflection from the impedance, measuring the input voltage to the reflected voltage ratio, so as to calculate the discontinuous impedance.

3, available network analyzer data measured in the frequency domain to calculate and display the network step and impulse response of the network as a function of time. Make in the reflection and transmission of the traditional TDR capability increases the potential for measurements in frequency band limited networks.

In reflection mode the network analyzer measures the reflection coefficient as a function of frequency. This reflection coefficient can be viewed as a transfer function of the incident and reflected voltages. The inverse conversion converts the reflection coefficient into a function of time (impulse response). The step and impulse responses can be calculated by convolving this reflection coefficient with the input step or pulse. In transmission mode. The network analyzer measures the transfer function of the two-port device as a function of frequency. The inverse transform converts this transfer function to the impulse response of the two-port device. The convolution of this impulse response with the input step or pulse is used to calculate the step and impulse responses.
