Time Domain Reflectometers

Time Domain Reflectometer STDR-65

We offer appropriate TDR systems for a variety of applications. Our "65" TDR family is the optimal solution for lab & production applications with a rise time in the picosecond range and extremely low jitter. The systems are ideally suited for the measurement of wave impedances and S-parameters on PCBs with signal bandwidths up to 10Gbps (single-ended & differential).

With the DTDR-800, a device is available that is ideally suited for measuring cables. Wave impedances can be determined or cable faults can be detected and localized.

The ATDR-100 is another specialized system designed for the purpose of rapid testing of PCBs. The device is especially suitable to fulfill recurring measurement tasks (e.g. impedance test coupons).


RF Multiplexers

DMXU-D4-A

Sequid launches its new RF multiplexer series, the latest differential system can be used up to 10GHz. The series will be further expanded soon and can be used for testing multi-channel cables and systems.

SMA Adapters

SMA Adapters

We offer various high-frequency SMA adapters for measuring common cable types, e.g. USB, HDMI, Display Port, RJ-45. If the adapter you need is not listed, please contact us, as we are constantly expanding our product range.


STLC - the cost-effective Tool for Impedance Calculations


STLC - the cost-effective Tool for Impedance Calculations

We offer the cost-effective Sequid Transmission Line Calculator (STLC) for the calculation of line impedances on PCBs. With the STLC tool you have the possibility to calculate the wave impedance for all common line types using a powerful 2D field solver method. We would be pleased to inform you about prices and conditions.

Should you have any questions or would you like to test the STLC tool for 2 weeks free of charge? Then call us or use the contact form. We are looking forward to your message.


Broadband dielectric Spectroscopy

Broadband dielectric Spectroscopy

Sequid GmbH's many years of experience in the field of dielectric spectroscopy has been consistently implemented in an optimal way in the form of the high-quality SDM-G10 coaxial sensor and user-friendly software for rapid measurement of the dielectric properties of materials.

The SDM-G10 sensor can be used up to frequencies of 10GHz. The software can be used in combination with the "65" TDR family as well as with commercially available network analyzers and/or coaxial sensors.

Development & Consulting Services

Development & Consulting Services

High frequency PCB design is becoming increasingly important in digital devices and embedded systems. If design rules for reflection-free transmission of high-speed clock signals are not observed, the functionality of the system often turns into a gamble. Our experts will be happy to advise you on questions of RF circuit design and general RF measurement technology.
