The CS2389 4G Signal Analyser is the replacement for the Dycon D2377 signal tester.
The CSL Dual CS2389 updates the design and function of this popular 4G Signal tester with a new touch screen interface. It is intended to be used to identify the optimum location for your cellular connected device prior to installation by searching all local base stations. It feeds back the network availability, radio technology (2G/3G/4G), Bit Error Rate (BER) and signal strength.
The CS2389 Signal tester is supplied as standard with the rubber protective boot / cover, and comes with a stylus, world charger, USB cable and SIM adapters
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.
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).
To ensure that a consistent approach is used to all Radio Access Technologies (RAT) – such as 2G, 3G and 4G – a new, more accurate method for calculating percentage of the signal strength has been introduced. The RSSL is not based on CSQ readings alone provided by the radio module, but is calculated from the raw data received from the network readings. The value is mapped through the whole range and is independent for each RAT. The value calculation includes both signal strength and signal quality measurements.
RSCP: -80 dBm
RSRQ: -4 dB
CSQ: 19
RSSL: 67%
