Identify the optimum location for your connected device prior to installation by using a 4G Signal Tester.

The CS2389 Signal Analyser is designed to relay accurate and essential data, to ensure the best position for your installation every time. It searches all the local base stations to give you an accurate reading of the major networks available, measuring and displaying radio technology, signal quality and radio signal strength. It provides information for 4G, 3G and 2G technologies and can also perform local Wi-Fi (2.4Ghz) surveys.

By connecting the aerial of your device to the Signal Analyser, you can utilise the live monitor function to find the optimum installation location. The Signal Analyser is ideal for installations of alarm signalling systems, 4G routers, parking meters/smart meters, Telecare products and many more applications.

Do I need to use a SIM?

A SIM is not needed for surveys it is only required when using monitor mode. The SIM used must be at least the same RAT (ie 2G/3G/4G) that you are looking to monitor, however it does not need to be on the same network.

Can I use my own SIM?

Yes, any SIM can be used as long as the pin code function has been removed. If you wish to use a micro or nano SIM, the SIM carrier provided must be used to make it the required size and ensure it fits into the device correctly.

I am running a survey but want to cancel?

While a survey is running you cannot cancel or complete any other actions, you must wait for the survey to complete or power off the device.

What is the difference between battery saver and auto turn off?

Battery saver puts the radio module into sleep mode and dims the brightness off the screen to save battery power. Auto turn off enables you to select a time that if the unit is not in use it will automatically power off to conserve battery power (as standard this is set to 5 minutes).

Why can’t I see all the networks? (in single network or monitor mode)

If you can’t see your preferred network try refreshing the network. After this refresh the networks available in your location will be displayed, if you still can’t see your chosen network it may be that it is not available in that area.

What do the icons mean?

If you are unsure what the function of an icon is you can use the self help function to display a description (press and hold the icon for 3 seconds).
