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.
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.
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.
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.
