Rf-explorer 3g combo - spectrum analyser.

Rf-explorer 3g combo - spectrum analyser.

RF enthusiast have limited themselves to cheap "RF Power Detector / Frequency counter" devices in the past. But these are limited to display data for a single point of maximum power, and traditionally power metrics are too unreliable, in the order of 20dB or even 30dB inaccuracy.

In contrast, a spectrum analyzer like RF Explorer will display full frequency spectrum in the band, including carrier and modulated shape, will display Spread Spectrum activity if that exist, and will show bandwidth to monitor collisions, frequency deviation from expected tone, etc.

This is the most advanced RF Explorer yet, covering 15Mhz to 2700Mhz covering all of the ISM bands, the wifi bands and many more. Similar spectrum analysers covering these frequencies can cost tens of thousands of pounds!

The 3G Combo model is a handheld digital spectrum analyzer, a very affordable tool for work in all popular frequency bands. It is based on a highly integrated frequency synthesizer and double balanced mixer which offers high performance, compact size, low consumption and low cost.

It has been designed to be used equally well outdoor and indoor, and can be connected to a PC for extra functionality using standard mini-USB 2.0 connector.

This model includes a WSUB1G baseline unit plus an RFEMWSUB3G Expansion Module conveniently assembled and tested. It comes with two SMA connectors and two antennas,a nice Nagoya NA-773 wideband telescopic antenna for all Sub-GHz frequencies and a whip helical for 2.4GHz band. Additional, specific band antennas may be needed to cover efficiently some of the frequencies supported.

The combination of these two models offer the wide band coverage of the WSUB3G module, together with the highest sensitivity and quick response of the WSUB1G model for the popular sub-1GHz frequencies.
