Introducing RF Explorer Spectrum Analyzer Product Family
What is RF Explorer Spectrum Analyzer?
RF Explorer is an affordable Handheld Spectrum Analyzer designed from scratch to be a sort of Swiss Army Knife for the specific needs of digital radio frequency communication.
Commercial high-end spectrum analyzers are traditionally expensive and bulky, in the order of many thousand dollars, and you need significant expertise to master them. RF Explorer offers 90% of what a high-cost unit will do for RF digital band communication, at 5% of the cost. Additionally, it can be carried on easily anywhere and used outdoors efficiently for hours with a single battery charge.
RF Explorer Spectrum Analyzers and Signal Generators provide unique capabilities including signal detection and hunting, interference and collision assistance, pre-compliance EMC testing, and many other use cases.

The RF Explorer Standard models include 7 functional buttons on the front side. The unit also includes at least one RF connector in 50-ohm impedance standard SMA format.
All models have an SMA left connector installed and, optionally, some models have a second SMA connector at the right position for extended range and functionality.
The unit will automatically start running on USB power when a compatible mini-USB cable is connected
