3 | This OsmocomBB firmware build is able to measure received signal strength over all channels that the hardware supports. |
||
4 | |||
5 | It has two modes: ARFCN view and Spectrum view |
||
6 | |||
7 | Depending on your hardware capabilities, this firmware is able to take measurements in all four bands in both uplink and downlink. |
||
8 | |||
9 | Uplink measurements always require the [wiki:Hardware/FilterReplacement] |

16 | * an indication of the ARFCN currently selected |
||
17 | * an indication of the band (DCS/PCS) for ARFCNs that exist in both bands |
||
18 | * the Rx Level in dBm |
||
19 | * a bar graph vor visualizing the RSSI |
||
20 | * an optional audible indication (beep tones) corellated with the RSSI |
||
21 | |||
22 | You can use it the following way: |
||
23 | * Enter the digits of an ARFCN on the numeric keypad followed by the Enter soft-key |
||
