With the rapid development of satellite communications and millimeter-wave applications, a reliable, versatile, and scalable test and access system has become essential to ensure secure operations and technological innovation. The integration of millimeter-wave universal measurement instruments with the VSAT (Very Small Aperture Terminal) system addresses requirements in satellite TV reception, broadcasting, and satellite network access, while also supporting any TCP/IP-based satellite communication applications. By combining antenna systems, transceiver modules, and codec units, the solution provides robust support for point-to-point, star, and fully meshed network topologies.

The antenna subsystem features a 1.2-meter prim-focal and offset design, operating at 18.5–19.5 GHz for reception and 28.7–29.5 GHz for transmission, with excellent cross-polarization performance. The transceiver module operates at 19.075 GHz (Rx) and 28.875 GHz (Tx), delivering 55 dB gain with an output power up to 37 dBm. The codec unit complies with DVB-S standards, supporting QPSK modulation, MPEG-2 video, AAC audio decoding, and multiple I/O interfaces including HDMI and RCA. Designed for extreme environments, the terminal ensures stable performance across -40 to 60℃ and under mobility loads of up to 80 km/h.

On the measurement side, Vector Network Analyzers (VNA) and Scalar Network Analyzers cover a wide frequency range from 26.5 to 170 GHz. The VNA performs automatic S-parameter measurements, including both two-port and four-port devices, with high accuracy in amplitude (±0.66 dB) and phase measurements. The scalar analyzer focuses on return loss, gain, and VSWR measurements, widely applied in amplifier, mixer, filter, and multiplexer testing. Both systems support Ethernet and RS-232 interfaces, enabling seamless integration into automated test environments.

For non-contact monitoring, the “RVS-36P” and “RVS-94” microwave vibration sensors offer high-resolution displacement, velocity, and acceleration measurements. Utilizing electromagnetic wave detection, they eliminate mechanical contact errors and are ideal for monitoring lightweight, high-speed, or high-temperature components.

Dedicated to radar applications, the system includes a multi-channel Tx/Rx module capable of echo amplification and frequency conversion within the 9.2–9.6 GHz range, delivering up to 8W output power with a noise figure below 3.2 dB.

In terms of power measurement and signal synthesis, the microwave power meter spans from 0.045 to 170 GHz, measuring both CW and pulsed signals with high precision. Signal synthesizers and generators provide AM/FM modulated or unmodulated microwave oscillations, supporting USB, RS-232, and Ethernet connectivity, making them suitable for laboratory testing, device debugging, and production line integration.

Overall, this solution combines robust satellite communication capabilities with advanced millimeter-wave measurement functions. On the communication side, it ensures high-speed, stable, and low-latency satellite links; on the measurement side, it provides a comprehensive, high-precision microwave testing platform. Its versatility makes it a powerful tool across broadcasting, defense communications, radar navigation, electronic engineering, and scientific research fields.
