Vector Network Analysis Component Characterization

RF component and system characterization is critical to emerging test requirements for all connected electronics. Whether designing products for IoT, WiFi, Bluetooth, or 5G analyzing and understanding the challenges and capabilities of the RF design are central to product design and success. SIGLENT's expanding solution portfolio for RF test requirements can grow with your application needs to extend into new frequencies and more complex characterization while providing quality, capability, and value.

Mixer Measurements up to millimeter wave


Engineers often need to evaluate mixer performance, including conversion loss, phase and group delay, the 1 dB compensation point, isolation between ports and port VSWR. Phase and group delay can be measured with a VNA equipped with Vector Mixer Measurement function. While the others can be achieved with Scalar Mixer Measurement function. In this application note, we give brief introduction about scalar measurements.

TDR Video

The SNA5000A’s complete, enhanced TDR test mode enables a statistical modeling of signal response to an established digital communication method. The user can set the noise, levels, and bit rate of the test signal and the TDR measurements visually shows the outcome of an eye diagram measurement. Standard and customizable Eye Mask tests are included. Test the complete system for throughput, bandwidth, and noise characteristics by injecting jitter into the described test signal.
