ENUM FE_SEC_VOLTAGE(9)

💜 enum fe_sec_voltage(9) 💜

okay bestie, so this is a page straight out of the Kernel API Manual, and it's genuinely one of the smaller ones — like, a little snack of a manpage. it's about one enum that controls the DC voltage feeding your LNBf. that's it. that's the whole vibe. and honestly? she's iconic for it.

---

✨ NAME ✨

enum fe_sec_voltage — the DC Voltage used to feed the LNBf 🛰️

---

🌸 SYNOPSIS 🌸

enum fe_sec_voltage {
    SEC_VOLTAGE_13 ,
    SEC_VOLTAGE_18 ,
    SEC_VOLTAGE_OFF

};

like, look at her. three constants, zero chaos. we love a concise queen 👑

---

🎀 Constants 🎀

so here's what each one actually does, no cap:

• SEC_VOLTAGE_13 — outputs 13V to the LNBf ⚡ (yes, thirteen volts, and yes, we're being precise about it)
• SEC_VOLTAGE_18 — outputs 18V to the LNBf 🔥 (bigger number, bigger energy, still just volts)
• SEC_VOLTAGE_OFF — literally does not feed the LNBf with a DC voltage 💀 like, she's sitting this one out, respectfully

ok but real talk: these are voltages going into hardware, so don't just vibe-pick one. they mean exactly what they say and nothing more 🙈

🦋 SEE ALSO 🦋

bestie, this is the part where the manpage goes absolutely feral with cross-references, and i'm obsessed. it points you at the Kernel file ./include/uapi/linux/dvb/frontend.h and then just keeps going:

enum fe_caps(9), struct dvb_frontend_info(9), struct dvb_diseqc_master_cmd(9), struct dvb_diseqc_slave_reply(9), enum fe_sec_tone_mode(9), enum fe_sec_mini_cmd(9), enum fe_status(9), enum fe_spectral_inversion(9), enum fe_code_rate(9), enum fe_modulation(9), enum fe_transmit_mode(9), enum fe_guard_interval(9), enum fe_hierarchy(9), enum fe_interleaving(9), enum fe_pilot(9), enum fe_rolloff(9), enum fe_delivery_system(9), enum atscmh_sccc_block_mode(9), enum atscmh_sccc_code_mode(9), enum atscmh_rs_frame_ensemble(9), enum atscmh_rs_frame_mode(9), enum atscmh_rs_code_mode(9), enum fecap_scale_params(9), struct dtv_stats(9), struct dtv_fe_stats(9), struct dtv_property(9), struct dtv_properties(9)

that's a whole friend group right there 🫶 go say hi to all of them.

and that's the page!! short, sweet, extremely specific about voltage. mwah 💅

signing off: this one lives over at ./include/uapi/linux/dvb, dated October 2026 — catch you in the next manpage, love u, bye 🎀✨
