Table 7: Trigger violations
Violation Description
T
The instrument triggers whenever the signal violates the mask (above the line).
F The instrument triggers whenever the signal has no points in the mask.
T>F
Onetransitiondefines the trigger event. The signal must go out of the mask (no violation)
after being inside of the m ask (violation).
F>T
Onetransitiondefines the trigger event. The signal must go into the mask after being
outside of t
he mask.
T>F>T
Two transi
tions define the trigger event. The signal must start inside of the mask, cross
outside of the mask, and then cross back into the mask.
F>T>F
Two transitions define the trigger event. The signal must start outside of the mask (no
violation), cross into the mask, and then cross back outside of the mask.
Controlling Acquisitions
When two or more displays are open, one display controls the acquisition system. The acquisition requirements for the
selected display set the acquisition hardware parameters. While the acquisition parameters are optimized for the selected
display, they might not be ideal for other displays. In this case, the other displays might be unable to m aintain optimum
performance and consequently might be unable to produce results. (This also happens when you analyze recalled data:
measurements attempt to deliver results, but may not be able to comply w ith all their settings.)
You can specify which display controls the hardware a cquisition parameters by clicking anywhere in that display. When there
are multiple displays, the highlighted display controls the hardware acquisition parameters.
In this example, there are two displays, a
Spectrum display and a DPX Spectrum
display. The highlighted title bar on the
Spectrum display indicates that it is the
selected display.
The check mark indicator in the upper
left corner of the display indicates that
acquisition hardware is optimized for the
Spectrum display.
Some displays do not control the acquisition hardware. These displays just show the captured data. Some displays share
the same parameters. If any of one of these displays in such a family controls the acquisition hardware, then the acquisition
pa
rameters are optimized for all of the displays in that family.
