Differential Time Domain Reflectometer DTDR-65

The Sequid DTDR-65 is optimized for an extremely stable operation. Due to sophisticated time base generation techniques in combination with proprietary correction algorithms the DTDR-65 features a vertical and horizontal stability, which is usually reserved for the high-price segment. Furthermore, the DTDR-65 grants this stability over a wide temperature range without the need for recurring calibrations, making it absolutely unique.

Software

Applikationen

Differential & Single-Ended Impedance

Measure wave impedance profiles of differential and single-ended transmission lines, connectors and cables. Gather a deeper insight in your systems and use this feature for pre-compliance testing, optimizing signal integrity (SI) and for quality assessment. It is also perfect for series impedance test coupon measurements.

Common-Mode Impedance

Common-mode impedance is an essential parameter in the design of electronic systems. It is important to take care of it with respect to signal integrity (SI), EMC compliance and noise rejection, making circuits more reliable and resistant to interferences.

Return Loss (RL) — the S-Parameter S₁₁

Measure the single-ended or differential return loss S₁₁ in the frequency range up to 10GHz — on PCBs, in cables and connectors. The differential return loss (mixed-mode parameter SDD) is determined here with a true differential measurement signal.

Return & Insertion Loss (RL/IL) — the S-Parameters S₁₁, S₂₁, S₁₂, S₂₂

The 2x2 scattering matrix [S] characterizes how signals are transmitted and reflected in a 2-port network, being extremely useful for analyzing transmission lines, filters, connectors or amplifiers.

Mixed-Mode S-Parameter

Mixed-mode S-parameters describe the behavior of differential and common-mode signals, essential in high-speed digital and RF circuit and PCB design.

Series Measurement for Quality Testing

The DTDR-65 is a cost-effective and reliable solution for series production and quality testing, equipped with a fully integrated ESD protection unit.

Skew Measurements

With the DTDR-65, you can perform high-precision skew measurements to ensure a high level of signal integrity.

Testing of Electrical Connections

Wave impedance measurements help optimize electrical connections by ensuring impedance matching, minimizing signal reflections and maximizing power transfer.

Fault Detection & Localization

The detection & localization of cable faults is a very traditional application of TDRs (also known as cable radar).

Dielectrics of Cores & Prepregs

Sequid's novel dual-line technology facilitates identifying the dielectric constant of your substrates in frequency range up to 5GHz.

Dielectric Spectroscopy (Complex Permittivity)

Measuring the frequency dependent complex permittivity of materials by means of an open-ended coaxial line sensor is an established method in the scientific community.

Transmitted & Reflected Step Responses

Evaluating step responses in reflection and transmission can be a very helpful tool, particularly useful for high-speed systems analysis. TDR measurements are also used for measuring diverse environmental parameters.
