Figure 5-3. Transitional Acquisition Mode
Acquisition Modes
You can use the external timing analyzer in one of three modes:
transitional, standard (data acquisition), or glitch (data and glitch
acquisition).
Transitional
In the transitional mode, data is sampled at 100 MHz, but stored only
when an input transition (on any channel) is detected. A time tag is
also be stored so that the data can be accurately placed in the display.
This mode allows the effective time window stored to be increased
while maintaining resolution.
The number of data transitions stored depends on the incoming data
transmission rate. The minimum number of data transitions that will be
stored is 128. Because time tags are also stored, the maximum number
of transitions that can be stored is 512. See figure 5-3.
