RF Remote Control Frequency Tester

Simply place the remote on the detection area and press a button: the display shows the transmit frequency. It is the quickest way to find out whether a remote uses the most common frequencies, such as those around 320, 434 or 868 MHz used by automatic gates, alarms and car keys. The CNBJ-501 remote frequency tester helps you choose the right replacement or duplicate.

Infrared Remote Control Check

When an IR remote is pointed at the instrument's receiver, the INPUT indicator lights up as the signal is received: in seconds you know whether the TV, air-conditioner or set-top box remote works, or whether the fault lies in the appliance. Discover all the details of the CNBJ-501.

Compatibility and applications

Suitable for radio remotes between 100 MHz and 1 GHz (gates, garages, alarms, car keys) and for infrared remotes of TVs, air conditioners and household devices. It measures compatible signals within its stated limits and does not replace a spectrum analyzer.
