Built to be trusted.
A handheld RFID signal analyzer you read off the front panel in seconds — and log over USB when you want a record. Here's what's inside RF Ranger.
Calibrated, lab-grade readings.
RF Ranger is a calibrated instrument suitable for scientific lab testing, so the decibel numbers you read are accurate. Its directional internal antenna covers the full 850–950 MHz band that RFID race timing runs on, letting you aim at one antenna or ramp without picking up unwanted signals from the air around you.

Frequently asked
Questions timers ask about RF Ranger
How to test an RFID timing system, what RF Ranger measures, compatibility, software, and battery — the things timers want to know before they buy.
What is the RF Ranger?
RF Ranger is a calibrated handheld 850–950 MHz RFID signal analyzer from Innovative Timing Systems. You aim its directional internal antenna at a timing antenna or ramp and read the signal strength in decibels right off the front panel — so you can verify that an RFID race timing system is reading at full power in under a minute, with no computer and no software.
How do I test or verify my RFID timing system with RF Ranger?
RF Ranger is an RFID timing system tester: power it on, aim the directional antenna at each timing antenna, and read the signal strength in dBm on the front-panel LEDs. In under a minute you can confirm every antenna is reading at full power before the gun goes off, catch weak cables and connectors before they cost you reads, and benchmark a reference baseline for every system you own.
Does RF Ranger work with any timing system, or only Jaguar?
Any timing system. RF Ranger covers the full 850–950 MHz band that RFID race timing runs on, so it works with every RFID timing system in the world — not just Innovative Timing Systems' Jaguar decoders. It measures the radio signal itself, so the brand of decoder or antenna doesn't matter.
How accurate is RF Ranger?
RF Ranger is a calibrated instrument suitable for scientific lab testing, so the decibel readings you take are accurate — and the decisions you make from them are sound. It's built to be trusted as a measurement tool, not just a go/no-go indicator.
Do I need a computer or software to use RF Ranger?
No. The front-panel LED readout shows signal strength in decibels with no computer, no app, and no configuration — it runs standalone on its rechargeable battery. When you want to log and benchmark, you can optionally plug it into a Windows PC or tablet over USB and capture signal strength over time with the free rfRanger Viewer software, but that's only needed for data capture.
Can RF Ranger log signal data over time?
Yes. Plug RF Ranger into a Windows tablet or PC over USB and the free rfRanger Viewer software captures signal strengths over time. Use it to benchmark your components, compare gear across deployments, and find weak links before they cost you reads on race day. The software is free to download from our website — no license and no subscription.
How long does the RF Ranger battery last?
RF Ranger runs for hours of use on a single charge of its internal rechargeable battery, so it's ready when race morning comes. Because the front-panel readout needs no computer or external power, you can walk the whole course and check every antenna and ramp on battery alone.
What problems can RF Ranger catch before a race?
RF Ranger verifies your entire RFID timing system in under a minute: confirm every antenna is reading at full power, identify weak cables and connectors before they cost you reads, and build a reference baseline you can re-check at every event. It turns “I think the system is fine” into a number you can read straight off the front panel.
No more guessing. No more surprises.
Verify your entire RFID timing system is performing at peak — every event, every time.
