Typical Signal Level for Stable Trigger
ing
Same as DC coupled limits4 for frequen
cies above 60 Hz. Attenuates signals
below 60 Hz.
Three and one half times the DC coupled
limits.4
One and one half times times the DC
coupled limits4 from DC to 30 kHz. Atten
uates signals above 30 kHz.
One and one half times the DC coupled
limits4 for frequencies above 80 kHz. At
tenuates signals below 80kHz.
1The trigger position errors are typically less than the values given here. These values are for triggering signals having a slew
rate at the trigger point of ±0.5 division/ns.
2The waveform interval (WI) is the time between the samples in the waveform record. Also, see the footnote for the characteris
tics Sample Rate Range and Equivalent Time or Interpolated Waveform Rates in Table 411 on page 412.
3The minimum sensitivity for obtaining a stable trigger. A stable trigger results in a uniform, regular display triggered on the
selected slope. The trigger point must not switch between opposite slopes on the waveform, and the display must not roll"
across the screen on successive acquisitions. The TRIG'D LED stays constantly lighted when the SEC/DIVsetting is 2 ms or
faster but may flash when the SEC/DIVsetting is 10 ms or slower.
4See the characteristic Sensitivity, Edge Type Trigger, DC Coupled in Table 43, which begins on page 45.
