dvbv5-fe-tool is a command line tool for digital TV services that is compliant with version 5 of the DVB API, and backward compatable with the older v3 DVB API. It was developed as part of DVBv5 Tools suite, which resides in the v4l-utils git repositiory [1].

For other dvbv5 tools, please see the main article.

dvb-fe-tool is a tool to inspect and change the tuning parameters directly at the Digital TV frontend. If called without any parameter, it will show the device capabilities:

$ dvb-fe-tool 
Device DRXK DVB-C DVB-T (/dev/dvb/adapter0/frontend0) capabilities:
     CAN_FEC_1_2
     CAN_FEC_2_3
     CAN_FEC_3_4
     CAN_FEC_5_6
     CAN_FEC_7_8
     CAN_FEC_AUTO
     CAN_GUARD_INTERVAL_AUTO
     CAN_HIERARCHY_AUTO
     CAN_INVERSION_AUTO
     CAN_MUTE_TS
     CAN_QAM_16
     CAN_QAM_32
     CAN_QAM_64
     CAN_QAM_128
     CAN_QAM_256
     CAN_RECOVER
     CAN_TRANSMISSION_MODE_AUTO
DVB API Version 5.10, Current v5 delivery system: DVBC/ANNEX_A
Supported delivery systems: 
    [DVBC/ANNEX_A]
     DVBC/ANNEX_C
     DVBT

It can also be used to change some parameters. For example, if one wants to run a legacy DVBv3 application to work with DVB-C in Japan, it could do:

$ dvb-fe-tool -d dvbc/annex_c

It can also be used to get the current settings:

$ dvb-fe-tool -g
...
Got parameters for DVBC/ANNEX_A:
FREQUENCY = 573000000
MODULATION = QAM/256
INVERSION = AUTO
SYMBOL_RATE = 5217000
INNER_FEC = NONE
