At the Terahertz Measurement Facility we offer a flexible range of services for use in both industrial and academic research and development projects.
The Keysight N5247B PNA-X 10 MHz to 67 GHz network analyser (pictured above) is capable of measuring, to a high degree of accuracy, the full two-port scattering parameters, (both magnitude and phase) of microwave devices in the frequency range from 10 MHz to 1.1 THz using the frequency converter units, supplied in pairs to permit full two-port measurements.
The broadband modules, equipped with 1 mm coaxial connectors, operate within the 10 MHz to 110 GHz range. Coaxial to waveguide adapters and frequency converter units further extend the capability for full two-port measurements to cover the following specific frequency bands:
- WR Band Frequency Range
- WR15 50 GHz – 75 GHz
- WR12 60 GHz – 90 GHz
- WR10 75 GHz – 110 GHz
- WR8 90 GHz – 140 GHz
- WR5.1 140 GHz – 220 GHz
- WR3.4 220 GHz – 330 GHz
- WR2.2 325 GHz – 500 GHz
- WR1.5 500 GHz – 750 GHz
- WR1.0 750 GHz – 1.1 THz
The system includes a 120 GHz power sensor, and frequency converter units are supplied with a power table that characterizes each head for power versus frequency. This feature eliminates the need for a power meter to perform source power calibration. Long interface cables allow for at least 10 meters of separation between the two test ports, facilitating antenna and propagation measurements.
This equipment can be used in in performing scattering and propagation measurements, measurements of material properties, and characterising RF to THz components such as filters, amplifiers, mixers, antennas and diplexers, which will be the building blocks for THz communications systems, remote sensing systems, radars, imaging systems and medical diagnostic systems.
We will provide technical support on usage of the system including support for software tools such as Spectrum Analyser, Time Domain, Convertor Measurements, Gain Compression, Intermodulation Distortion Measurement and also Material Measurements.
