Minimal signal level to trig acquisitions

I'm using my RP card to acquire signal around 10 - 30 mV (and around 1 kHz) on RF inputs. After few tests, I realize that even if I put ACQ:TRIG:LEVEL at 0, a signal smaller than 20 mV does not trigger the acquisition. More precisely, this minimal level varies between 17 and 21 mV.
Does anyone have seen that ? Does someone know if it is possible to lower this minimal level ?
20 mV is not a so small signal, any traditional oscilloscope can trigger with it.

I thank you for any answer you could give me !
