This OsmocomBB firmware build is able to measure received signal strength over all channels that the hardware supports.

It has two modes: ARFCN view and Spectrum view

Depending on your hardware capabilities, this firmware is able to take measurements in all four bands in both uplink and downlink.

Uplink measurements always require the [wiki:Hardware/FilterReplacement]

In the ARFCN view you get * an indication of the ARFCN currently selected * an indication of the band (DCS/PCS) for ARFCNs that exist in both bands * the Rx Level in dBm * a bar graph vor visualizing the RSSI * an optional audible indication (beep tones) corellated with the RSSI

You can use it the following way: * Enter the digits of an ARFCN on the numeric keypad followed by the Enter soft-key * Use the Left/Right buttons to decrease/ increase the currently shown ARFCN * Use the Up/Down buttons to increase/decrease the beep tone volume * Use the * (asterisk) button to enter spectrum view * Use the UL/DL soft-button to change uplink / downlink measurement

In the spectrum view, you get a graphical spectrum plot

You can use it the following way: * Use the Up/Down buttons to adjust the scale
