Spectrum Analyzer 50KHz-1.5GHz with SD Card Slot, Vector Network Antenna Analyzer for MF HF VHF UHF

Spectrum Analysis in a Compact Design This compact spectrum analyser brings professional-grade measurement capability to a portable format, covering a frequency range from 50KHz to 1.5GHz across MF, HF, VHF and UHF bands. Whether you are working on antenna tuning, filter alignment or general signal troubleshooting, the unit provides a practical solution for bench and field use alike. The integrated SD card slot accepts cards up to 32GB, allowing you to store measurement data and screen captures for later review or documentation. Extended Frequency Coverage and Dynamic Performance The instrument uses an improved frequency algorithm that takes advantage of the odd harmonic extension of the SI5351 synthesiser, enabling measurements up to 900MHz. In the direct output range of 50KHz to 300MHz, the analyser delivers more than 70dB of dynamic range. When operating in the extended 300MHz to 600MHz band, dynamic performance remains above 60dB, while the 600MHz to 900MHz range still achieves better than 50dB. This consistent performance across the spectrum makes the unit suitable for a wide variety of RF measurement tasks. Shielded Construction for Reliable Readings A metal shielding enclosure helps reduce external electromagnetic interference, which in turn supports more accurate and repeatable measurements. This is particularly valuable when working in environments with multiple active RF sources, as the shielding minimises stray pickup that could otherwise distort the trace on screen. PC Software and Data Export The analyser comes with simple and practical PC control software that allows you to export touchstone files in SNP format. These files can be imported into various wireless design and simulation packages, making it straightforward to transfer real-world measurement data into your engineering workflow. The combination of hardware measurement and software export provides a convenient bridge between field testing and computer-based analysis.
