TRIGGERING
Sensitivity
Ac Coupled Signal: 0.3 div internal or 50 mV external,
from 60 Hz to 25 MHz ; increasing to 1.5 div, internal or
150 mV external at 100 MHz .
LF REJ Coupled
Signal: 0.5 div internal or 100 mV
external,
from 50 kHz to 25 MHz ; increasing to 1.5 div
internal or 300 mV external at 100 MHz . Attenuates
signals below about 50 kHz .
HF REJ Coupled Signal: 0.5 div internal or 50 mV
external , from 60 Hz to 50 kHz . Attenuates signals below
about 50 Hz and above about 50 kHz .
DC Coupled Signal: 0.3 div internal or 50 mV external,
from dc to 25 MHz; increasing to 1.5 div internal or 150 mV
external at 100 MHz.
