From The GC747A Manufacturer:
The RF Analyzer GC747A (JD747A) is an ideal tool for installation and maintenance of cellular base stations. The GC747A combines the functionality of spectrum analysis, cable and antenna analysis, and power measurements, covering all the measurements required for test, acceptance and troubleshooting the physical layer of cellular networks. The GC747A is equipped with one-button standards-based measurements for wireless signals and offers the full scope of common performance measurements of BTS antenna systems. Equipped with optional power sensors, the 747A becomes a highly accurate RF power meter with no additional cost. In addition, the 747A provides an interference analysis function to find intermittent interfering signals using a spectrogram display, signal strength meter, and signal ID capability. The GC747A has a standard built-in preamplifier that together with the interference analysis option provides the ability to identify and locate interfering signals as low as –155 dBm. The GC747A is the ideal field testing solution that combines portability, due to its lightweight design and battery extended operation, and performance, with its multifunction capability. The GC747A has a strong enclosure design for harsh environments, and its backlight key panel makes nocturnal maintenance tasks possible
Key Features:
Easy User Interface
The GC747A has a consistent and intuitive interface through its multiple functions providing a common menu structure that is easy to use. The GC747A has a built-in help capability which guides users through each measurement task. A screenshot of any functions can be saved as a graphics file for report generation and traces can be saved for post-analysis process into the instrument’s internal memory or external USB memory device. The stored data can be easily transferred to a PC using the USB 10/100 Ethernet ports. For file name editing, a rotary knob is integrated with an enter button providing convenience to choose and select alphanumeric characters easily.
Field Useable Design
The GC747A is compact and lightweight especially convenient for users performing field measurements. Its bright 8” color display provides visibility in daylight. And its backlight keys provide visibility on the dark. The GC747A has an operating temperature range from –10 to 55 Celsius, and its connector bay support was designed to protect the instrument’s connectors from drops or other external impacts exceeding the MIL-PRF-28800F class 2 specification. The instrument’s internal battery provides up to 3 hours of continuous operation. When an extended operation is necessary, a secondary battery can be installed in seconds. Alternatively, it is equipped with DC adapters for vehicles and AC adapters for standard line power. Convenience is absolutely necessary for the field. The GC746A is equipped with powerful one-button measurements for channel power, occupied bandwidth, spectrum emission mask, adjacent channel power ratio, and spurious emissions.
Multi-language user interface
The instrument’s architecture allows the graphical user interface to adapt to different languages, permitting localization around the world.
