Kaltman Creations introduces the worlds first low cost handheld, RF Spectrum Analyzer which provides any wireless user the ability to find occupied channels, interference and open RF spectrum. The Spectran HF-4040 reads signals from below the FM band to beyond the busy 2.4 gigahertz spectrum up to 4 gig with “drill down” to exact frequencies and power level, in any application. The Spectran HF-4040 provides data logging for unattended use and for “extended period” analysis of RF spectrum. This device takes the guess work out of wireless equipment frequency selection to provide reliable wireless operation of computer networks, audio, video, industial controls, building automation, intercom, lighting control, broadcasting and much more.
