4-Port Time Domain Network Analyzer QTDNA-300

The QTDNA-300 is a full 4-port time domain network analyzer. It is optimized for a very stable operation and therefore suitable for laboratory and industrial environments. Due to sophisticated time base generation techniques in combination with proprietary correction algorithms the QTDNA-300 features an excellent vertical and horizontal stability. In addition, the QTDNA-300 ensures this stability over a wide temperature range without the need for recurring calibrations, making it the ideal choice for quality assurance, industrial applications and in automated test Environments.

Applikationen

Return & Insertion Loss (RL/IL) — the S-Parameters S11, S21, ..., S43, S44

The 4x4 scattering matrix [S] characterizes how signals are transmitted and reflected in a 4-port network, being extremely useful for analyzing differential and 4-port transmission systems like transmission lines, filters, connectors and other 4-port DUTs.

Mixed-Mode S-Parameter - the S-Parameters SDD11, SDD21, ..., SCC12, SCC22

Mixed-mode S-parameters describe the behavior of differential, common-mode signals and mode-conversion, essential in high-speed digital cable and PCB design. Reflection (RL) and transmission (IL) measurements are supported.

Series Measurement for Quality Testing

The QTDNA-300 is a very cost-effective and reliable solution for differential cable series production and quality testing, equipped with a fully integrated ESD protection unit.

Differential & Single-Ended Impedance

Measure wave impedance profiles of differential and single-ended transmission lines, cables and systems. Gather a deeper insight and use this feature for pre-compliance testing, optimizing signal integrity (SI) and for quality assessment.

Common-Mode Impedance

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

Intra-Pair Skew Measurements

With the QTDNA-300, you can perform intra-pair high-precision skew measurements to ensure a high level of signal integrity by performing compliance testing. This parameter is particularly important in the automotive sector and other price-sensitive segments.

Propagation Time Measurements

High-precision propagation time measurements are supported. Make sure this critical parameter is within your customers specification by making highly accurate TDR-measurements. Applications that require high bit rates at moderate cable prices often require proof of quality.
