HTOOL SA8 Spectrum Analyzer and Signal Generator User Manual

1. Introduction

The HTOOL SA8 is a versatile device designed to display the signal spectrum in the frequency range from 35 MHz to 6200 MHz. It allows users to find the amplitude and frequency of spectral components, making it suitable for analyzing signals from various technologies including Wi-Fi, 2G, 3G, 4G, LTE, CDMA, DCS, GSM, GPRS, and GLONASS.

A key feature of the SA8 is its optional tracking generator function, which enables the measurement of frequency responses for passive or active devices like filters or amplifiers. With an external directional probe and proper calibration, the device can also measure VSWR (Voltage Standing Wave Ratio) and return loss modules.

The SA8 is built for field work, featuring a durable, lightweight design and low power consumption. This makes it an ideal tool for service centers and teams performing high-frequency on-site analysis for commissioning and repairs. It is also a valuable instrument for repair shops and radio amateurs.

1. Navigate to the main menu.
2. Select the 'Language' option.
3. Choose from English, Russian, or Chinese.

7.4. Spectrum Analysis

Connect the signal to be analyzed to the RF IN port. Adjust the frequency range (SPAN), center frequency, and amplitude settings using the corresponding buttons or touch screen controls to view the desired spectrum.

7.5. Signal Generation

To use the device as a signal generator, select the generator mode from the menu. Configure the desired frequency and amplitude, then connect your receiving device to the RF OUT port.

7.6. Tracking Generator Function

For measuring the frequency response of devices (e.g., filters, amplifiers), enable the tracking generator function. This typically involves connecting the RF OUT to the input of the device under test, and the output of the device under test to the RF IN. An external directional probe may be required for certain measurements like VSWR and return loss, along with a set of calibration measures.

8. Maintenance

• Cleaning: Use a soft, dry cloth to clean the device. Do not use liquid cleaners or solvents.
• Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
• Battery Care: For optimal battery life, avoid fully discharging the battery frequently. If storing for extended periods, charge the device to about 50% every few months.
