The Sequid STDR-65 is optimized for an extremely stable operation. Due to sophisticated time base generation techniques in combination with proprietary correction algorithms the STDR-65 features a vertical and horizontal stability, which is usually reserved for the high-price segment. Furthermore, the STDR-65 grants this stability over a wide temperature range without the need for recurring calibrations, making it absolutely unique.
Measure wave impedance profiles of 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.
Measure the return loss S₁₁ in the frequency range up to 10GHz — on PCBs, in cables and connectors.
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.
Sequid's novel dual-line technology facilitates identifying the dielectric constant of your substrates in frequency range up to 5GHz.
The STDR-65 is a cost-effective and reliable solution for quality control in series production, equipped with a fully integrated ESD protection unit.
Wave impedance measurements help optimize electrical connections by ensuring impedance matching, minimizing signal reflections and maximizing power transfer.
The detection & localization of cable faults is a very traditional application of TDRs (also known as cable radar).
Evaluating step responses can be a very helpful tool, particularly useful for high-speed systems analysis. TDR measurements are also used for measuring diverse environmental parameters.
