RF Ranger

RF Ranger is a calibrated handheld signal analyzer that verifies your entire RFID timing system in under a minute. Aim its directional internal antenna at any antenna, cable, or ramp and read signal strength in decibels right off the front panel — no computer, no app, no setup. With lab-grade accuracy across the 850–950 MHz band it works with every timing system in the world, and free USB software lets you log readings over time to benchmark gear and catch weak links before they cost you reads.
