S-parameter measurement over distance in applications like over-the-air testing, large vehicle electromagnetic characterization, and insertion loss measurements on installed long distance cable runs becomes increasingly complicated as frequencies increase into the millimeter-wave (mmWave) region. At these frequencies using coax cabling to interface the DUT to a standard VNA becomes problematic because of the insertion loss and phase instability of coax cabling over long distances. To overcome these issues, high-performance VNAs, active signal conditioning hardware, and other components must be added to the typical test setup.
This webinar will discuss a new approach and methodology to making these distance measurements. You will learn more about the critical benefits of leveraging modular VNAs at higher frequencies to minimize distances between the DUT and the VNA port to make stable, repeatable measurements.
Who should attend:
Engineers, test engineers, and manufacturing who are conducting outdoor antenna range testing, OTA chamber installations, large vehicle (aircraft, ship) electromagnetic characterization (shielding, RF propagation), and long distance cable insertion loss measurements.
What you will learn:
- Example applications for long-distance VNA S-parameter measurements
- Existing setups using high-performance VNAs and additional components to overcome distance related measurement issues
- Disadvantages of current solutions and a different technological approach to overcoming these limitations
- A new modular VNA solution to S-parameter measurements over distances of 100+ meters
