Using Trigger Holdoff to Synchronize
Acquisition/Display on Complex
Signals
Triggering on simple repetitive signals is easy using standard edge
triggering. But if you need to synchronize your oscilloscope’s
acquisitions/display on more complex signals, such as an
amplitude-modulated signal, you will need to use your oscilloscope’s
trigger hold-off capability unless there is an external synchronization
signal available. This lab shows you how to use trigger holdoff to
achieve a stable trigger in the absence of a synchronization signal.
Make connections and perform initial setup:
1 To power the demo board, connect a USB cable between it and the
Agilent Infiniium 9000 Series oscilloscope.
You can also apply power by connecting the oscilloscope’s MSO
cable to the demo board’s 40-pin connector.
2 Connect the scope channel 1 probe to demo board CH1 and GND.
3 Make sure all other probes are disconnected from the
oscilloscope.
4 Turn the SELECT switch to position 1 (AM).
5 Press [Default Setup].
