Rental Partners - Four FieldFox Measurements You Can Perform on the Go
White Papers
Introduction
An engineer working in the field conducts routine maintenance on and troubleshoots deployed radio-frequency (RF), microwave, and millimeter-wave systems. On any given day, you may need to measure a variety of devices or signals — cables, antennas, over-the-air signals, or intermittent spurious signals — to ensure robust signal quality and uninterrupted service.
Successfully performing these functions requires a basic understanding of measurements and a portable, easy-to-use handheld instrument. This white paper outlines four common measurements you can perform in the field: real-time spectrum analysis (RTSA), noise figure, over-the-air (OTA) testing, and cable and antenna test (CAT).
1. Real-Time Spectrum Analysis
What is RTSA?
RTSA processes signal samples gap-free and generates measurements, such as scalar, power, or magnitude, that correspond to traditional spectrum analysis measurements.
RTSA measurements on the go
Signal interference over wireless networks is on the rise, resulting in poor signal quality that leads to dropped calls or choppy audio. It has a profound impact on wireless devices and communications, ranging from car radios to mission-critical applications such as public safety.
