Triggering the HP 54645D Mixed-Signal
Oscilloscope
The HP 54645D Mixed-Signal Oscilloscope allows you to synchronize
the oscilloscope display to the actions of the circuit under test by
defining a trigger condition.
The trigger types include edge, pattern, and advanced, allowing you to
match the complexity of the trigger to that of the data you want to
capture. The triggering modes include Auto Lvl, Auto, and Normal.
Advanced triggering consists of Glitch, Advanced Pattern, and TV.
Depending on the trigger selections and conditions, you can use
analog channels A1 or A2, Line, or D0-D15 for the trigger source.
MegaZoom Technology Simplifies Triggering
With the built-in MegaZoom technology, you can simply Autoscale the
waveforms, then stop the scope to capture a waveform. You can then pan and
zoom through the data to find a stable trigger point. Autoscale often produces a
triggered display.
