The ML4035-TDR is a state-of-the-art combination of a TDR and Digital Sampling Oscilloscope. The DSO performs accurate eyediagram analysis at 35 GHz to characterize the quality of transmitters and receivers, implementing a statistical under-sampling technique with comprehensive software libraries for eye measurements, jitter analysis and processing of NRZ/PAM4 data. The truedifferential TDR can determine the impedance profile and reflection loss on 4 channels simultaneously. It is designed and suited both for characterization as well as manufacturing. The 4 differential PPG ports can generate pulse patterns up to 58 Gbps NRZ, enabling Sdd21 measurements beyond 32 GHz. The ML4035- TDR can be configured to measure TDR with a range of 10 meters. It has a pulse rise time of 12 ps that allows to resolve impedance discontinuities as close as 1.5 mm apart. The dynamic range is 40 dB. The ML4035-32 is a 32 GHz variant that excludes TDR capability and can be used for applications such as TIA testing and for other BERT-Scope applications.
