Here you’ll find answers to the most common questions about spectrum analyzers. If you can’t find what you’re looking for, feel free to contact our team.
FAT100
What is the difference between FAT100 and FAT130 models?
The FAT130 extends the frequency range to 3.2 GHz and includes a tracking generator (5 MHz–1.6 GHz), making it suitable for higher-frequency applications and scalar network analysis.
Can I export measurement data for further analysis?
Absolutely. Data can be saved to USB flash drives or SD cards, transferred via USB/LAN, or managed through the included PC software for reporting and analysis.
What applications is the FAT100 spectrum analyzer best suited for?
The FAT100 is ideal for RF education, field maintenance, interference hunting, broadcast monitoring, wireless system installation, and R&D prototyping. Its portable design and high sensitivity make it perfect for both lab and on-site measurements.
Is the FAT100 suitable for outdoor use?
Yes. With an IP51 rating and rubber-armored housing, it resists dust and light moisture, making it reliable for outdoor and industrial environments.
FAT130
What are the main applications for the FAT130 Handheld Spectrum Analyzer?
The FAT130 is extremely versatile. Key applications include: Cellular Network Deployment & Optimization (5G NR, LTE, WCDMA, GSM), Interference Hunting & Spectrum Monitoring (with GPS geotagging), Broadcast & Wireless Communication System Maintenance, RF Component Testing (with optional tracking source), EMC Pre-compliance Testing, and Indoor/Outdoor Coverage Mapping (Drive Testing). It's designed for field engineers, technicians, and installers across telecom, public safety, broadcast, and industrial sectors.
What is the battery life, and can I use it while charging?
The standard internal battery provides approximately 2.5 hours of continuous operation on a full charge. Yes, you can operate the analyzer while it is connected to the included AC power adapter or car charger adapter, enabling uninterrupted work during long testing sessions.
How do I save and export measurement data in the field?
You have multiple convenient options: 1) Save directly to the 1GB internal memory. 2) Insert a USB flash drive and save data directly. 3) Connect to a PC via the Ethernet (LAN) cable for file transfer or remote control. The included Workbench PC software facilitates easy data management and analysis on your computer.
Is the display visible in bright outdoor sunlight?
Absolutely. A key design feature is its high-brightness 6.5-inch TFT color display, specifically engineered to remain clear and readable in direct sunlight. This ensures accurate interpretation of spectra and data during outdoor drive tests, tower work, or any field operation.
Does it support software updates, and how are they performed?
Yes, TFN provides firmware and software updates to enhance functionality. Updates are typically performed easily via a USB flash drive. The update files are placed on the drive, and the process is initiated through the system menu on the analyzer. Instructions are provided with update releases.
FAT150
What wireless standards is the FAT150 spectrum analyzer compatible with?
The FAT150 supports a wide frequency range from 9 kHz to 6 GHz, making it suitable for testing 2G, 3G, 4G LTE, and 5G NR signals, as well as WiFi, Bluetooth, and other RF applications.
How does the FAT150 achieve such high sensitivity in a portable device?
Through advanced all-digital IF architecture and an optional low-noise amplifier, the FAT150 minimizes internal noise, achieving a typical DANL of -165 dBm/Hz, allowing detection of very weak signals.
Can I use the FAT150 for outdoor field testing in bright sunlight?
Yes. The 7-inch touchscreen features a high-brightness mode and adjustable contrast settings, ensuring clear visibility even in direct sunlight or harsh outdoor environments.
How long does the battery last during continuous operation?
The built-in 7800 mAh Li-ion battery provides up to 4.5 hours of continuous use, sufficient for most field testing scenarios. It can also be powered via the included AC adapter.
What interfaces are available for data export and remote control?
The FAT150 includes USB Host/Device ports, a 10/100M Ethernet port, and supports file saving in CSV, PDF, and image formats. This allows easy data transfer, remote operation, and report generation.
RMT
What frequency model should I choose for 5G testing?
For Sub-6GHz 5G, the RMT716A (6.32GHz) or RMT719A (9GHz) is sufficient. If you work with millimeter-wave 5G (e.g., n257, n260 bands), the RMT740A (40GHz) is recommended for full coverage.
Can the RMT analyzer demodulate 5G NR signals?
Yes, it supports 5G NR demodulation, including beam analysis, PCI identification, EVM measurement, and SSB/PBCH decoding. It also performs LTE, GSM, and NB-IoT analysis.
How accurate is the interference location function?
When used with a directional antenna and GPS, the AOA-based positioning can achieve high directional accuracy. Multi-point mapping further improves location precision, ideal for tracking illegal transmissions or interference sources.
How long does the battery last during field use?
The built-in lithium battery provides ≥6 hours of continuous operation. An external power adapter or power bank can also be used for extended measurements.
Is software update supported?
Yes, TFN provides periodic firmware and software updates to add new features, support additional frequency bands, and improve measurement algorithms. Updates can be performed via USB or network connection.
