The PORTXVNSA SA5 Spectrum Analyzer is a compact, high-performance RF spectrum analysis instrument designed for wideband signal monitoring and measurement from 100 kHz up to 5.3 GHz. Ideal for RF engineers, amateur radio operators, wireless technicians, and hobbyists, the SA5 provides real-time spectrum visualization—with intuitive controls and a built-in display—without the need for bulky bench instruments.

Engineered for portable field use and bench testing alike, the SA5 enables users to analyze RF signal amplitude, frequency content, harmonics, spurious emissions, and interference across the RF spectrum. It’s suitable for troubleshooting wireless systems, verifying antenna performance, checking transmitter spectral purity, and monitoring environmental RF activity.

The SA5 Spectrum Analyzer delivers:

• Wide frequency coverage from 100 kHz to 5.3 GHz

• Real-time display of signal amplitude (dB) vs. frequency

• Adjustable sweep settings, including resolution bandwidth (RBW)

• Peak, average, and trace-hold display modes

• Marker readouts and span/center frequency adjustment

• USB-C connectivity for PC data export and external analysis

This combination of features makes the SA5 a versatile and portable RF test tool for antenna tuning, interference hunting, transmitter verification, and RF system characterization.
