1. Introduction
The HTOOL SA8 is a portable spectrum analyzer and signal generator designed for displaying signal spectrums within the frequency range of 35 to 6200 MHz. It is capable of identifying the amplitude and frequency of spectral components and supports various technologies including Wi-Fi, 2G, 3G, 4G, LTE, CDMA, DCS, GSM, GPRS, and GLONASS.
A key feature is its optional tracking function, which enables the measurement of frequency responses for passive or active devices like filters and amplifiers. With external accessories, it can also measure VSWR and return loss. The SA8 is built for field use, emphasizing durability, lightweight design, and low power consumption, making it suitable for on-site analysis, commissioning, and repairs.
