Free software makes it easy to expand the measurement capabilities in the lab and measure remotely via an Ethernet connection.

We also provide the programming manual, you can connect the SK9901 via RJ45 or usb and integrate it into your test solution.

The DTF function is a powerful tool for detecting and pinpointing faults, breaks, or impedance mismatches along RF transmission lines. Perfect for installation, maintenance, and troubleshooting, it allows users to quickly locate cable issues, reducing downtime and ensuring signal quality. This feature is ideal for telecom technicians, broadcast engineers, and RF field engineers who need precise, reliable fault detection in coaxial and other transmission cables.

The Comparator function allows for accurate phase and level comparisons between two ports, making it ideal for tuning phased arrays and other phase-sensitive RF systems. When used with a directional coupler, it can monitor forward and reflected signal power, providing critical insights into system performance and ensuring optimal alignment and signal integrity.

The Spectrum function leverages the VNA’s architecture to provide basic spectrum analysis capabilities, suitable for stable signal measurements. While not as advanced as a dedicated spectrum analyzer, it effectively handles many standard spectrum measurements, making it a practical tool for identifying and assessing steady RF signals in various applications.

The RF Source function generates reliable RF signals with support for continuous wave (CW) output and FM/ASK modulation, providing flexibility for various testing scenarios. It includes a 60 dB attenuation range, allowing precise control over signal strength, making it ideal for calibration, component testing, and system integration in RF applications.

The AF Source function generates audio frequency signals with support for continuous wave (CW) and FM/ASK modulation. It provides flexible routing options through either the BNC or RF port, making it versatile for audio signal testing, modulation experiments, and other applications that require low-frequency signal generation.
