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

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
