Zap Checker RF Detection
ZAP CHECKER products are ultra-sensitive instruments that detect and display Radio Frequency (RF) signals over a broad span of frequencies. They are a new generation of RF measurement tools that employ recently introduced IC technology to measure from very weak to ultra strong signals and differentiate analog from digital communications. They are ideal for bug detection, wireless installations, detection of covert bug devices, and detecting and locating undesirable signal sources such as interfering transmissions, bugs, RFI, noise and leakage.
All Zap Checker models are easy to use, small, handheld products with internal fixed antennas which require no adjustments. All models employ linear (regular) as well as logarithmic (compressed) amplification and detection. Each model has an analog meter and LED display. (The LED displays are visible from a distance and at night time.)
Most Zap Checkers have an audio output to hear signal strength levels and identify sources by their characteristic sounds. Some products have a switch enabled silent vibrator. The more professional models employ specialized external antennas and, in the case of the ABC 126, a high frequency band that filters out noise and interfering signals to allow for the highly sensitive detection of signals above 1.5 GHz. The ABC 126 also has a USB output connection for distant monitoring, remote powering and accessory switching.
