Measuring Functions
Auto Trigger
Auto Trigger is a great help especially when
you measure on unknown signals. However,
overshoot and ringing may cause
Auto to
choose slightly wrong MIN and MAX signal
levels. This does not affect measurements like
frequency, but transition time measurements
may be affected.
Therefore, when working with known signals
such as logic circuitry, set the trigger levels
manually.
Always use manual trigger levels if the signal
repetition rate is > 300 MHz or drops below
100 H
z (default), or below the low frequency
limit set by entering a value between 1 Hz and
50 kHz in the menu
Auto Trig Low Freq. You
can reach it by pressing
SETTINGS
