S3101 Series Cable And Antenna Analyzer

S3101 series cable and antenna analyzer is designed with latest technologies and can provide an accurate and fast measurement. Operator can measure VSWR, return loss, impedance, phase, DTF etc. with such a compact and low-weight box. S3101 is equipped with long-term battery, touch screen, and auto-adjust back light for easy site use.

S3101 series is perfect for cable and antenna system site test of telecommunication base stations. Tetra, GSM, PCS/DCS, CDMA, GPRS, WCDMA, CDMA200,TD-SCDMA, LTE etc. S3101B reaches 8GHz and brings more abilities to do higher frequency measurements.

S3101 also provides smith chart, phase display and can be easily used as a single port VNA.
