Operation
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 One transition de fi nes the trigger event. The signal must go out of the mask (no violation)
after being inside of the mask (violation).
F > T One transition de fi nes the trigger event. The signal must go into the mask after being
outside of the mask.
T > F > T
Two transitions de
fi ne 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 de fi ne 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 maintain 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 with all their settings.)
You can specify which display controls the hardware acquisition 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 DPX
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
parameters are optimized for all of the displays in that family.
