Kaltman Introduces Handheld RF Spectrum Analyzer

Kaltman Creations is out with an affordable handheld RF spectrum analyzer.

Intended to be the first in a series, the model is the Spectrum HF4040. The unit addresses channel selection, interference identification, RF system monitoring, testing and exposure limits. Its frequency range is from 10 MHz to 4 GHz making it suitable for analyzing VHF, UHF and 2.4 GHz environments.

The company said the timing of the product launch is notable thanks to “the exponential use of wireless technology along with the shrinking of some wireless bands. The increased challenges of identifying interference and finding available frequencies are in some cases becoming unmanageable.”

One area of concern, it notes, is in the UHF band where wireless microphone users are getting squeezed-out with the FCC’s UHF band reallocation and the DTV UHF mandate.

Kaltman Creations preconfigures the system’s 10 hot keys to address the more popular North America RF bands: Wireless Microphone, Wi-Fi, Assisted Listening, Telco/Cellular, Intercom and Radio/TV Broadcast. The user can reprogram the hot keys and manually set up any frequency sweep range.

The HF4040 system package is priced under $1,400.

The new company’s other products include a handheld motorized cable coiler and a cable tie product.
