for measurements of non-connectorized devices, test fixtures, probes or other structures are used to adapt from the coaxial interface of the test setup to the device under test (dut). for accurate measurements of the dut, these lead-ins and lead-outs need to be characterized, so that their effects can be mathematically removed, i.e. de-embedded from the measurement results.this application note provides practical hints to accurately characterize and de-embed these lead-in and lead-out structures with r&s vector network analyzers zna, znb, znbt and znd. as de-embedding is also essential in other test equipment like oscilloscopes, etc., this guide also describes, how lead-ins and lead-outs can be accurately characterized with a vna and then exported as an s-parameter file to be used by other test instruments.

pam-4 (4-level pulse amplitude modulation) has been introduced in high-speed serial data technology to reduce the bandwidth demands of ultra-high data rates. it uses only half the bandwidth per bit that would be required of conventional nrz (non-return to zero) modulation. but at the same time, pam-4 signaling complicates design and test at every turn. evaluation of channels is now just as important to system development as serializer / deserializer (serdes) testing and the challenges presented require a higher level of test and measurement performance than ever before. this paper investigates the evaluation complexities of pam-4 interconnects at high data rates.

vector network analyzers of t zna and znb family are able to measure magnitude and phase of complex s-parameters of a device under test (dut) in the frequency domain. by means of the inverse fourier transform the measurement results can be transformed to the time domain. thus, the impulse or step response of the dut is obtained, which gives an especially clear form of representation of its characteristics. for instance, faults in cables can thus be directly localized. moreover, special time domain filters, so-called gates, are used to suppress unwanted signal components such as multireflections. the measured data "gated" in the time domain are then transformed back to the frequency domain and an sparameter representation without the unwanted signal components is obtained as a function of frequency. as usual, other complex or scalar parameters such as impedance or attenuation can then be calculated and displayed.
