Table 8: TLA5000 trigger system (cont.)
Characteristic
Description
By event
Storage can be turned on or off; only the current sample can be stored. The event storage
control overrides any global storage commands.
Block storage
When enabled, 31 samples are stored before and after the valid sample.
Not allowed when glitch storage or setup and hold violation is enabled.
Glitch violation storage
The acquisition memory can be enabled to store glitch violation information with each data
sample when asynchronous clocking is used. The probe data storage size is reduced by one
half (the other half holds the violation information). The fastest asynchronous clocking rate
is reduced to 4 ns.
Setup and hold violation storage
The acquisition memory can be enabled to store setup and hold violation information with each
data sample when synchronous clocking is used. The probe data storage size is reduced by
one half (the other half holds the violation information). The maximum clock rate in this mode is
235 MHz.
1
Each use of External Signal In, glitch detector, setup and hold violation detector, or transition detector requires a trade-off of one word recognizer resource.
2
Any glitch is subject to pulse width variation of up to the channel-to-channel skew speci
fi
0.25 ns.
3
Any setup value is subject to variation of up to the channel skew speci
fi
cation. Any hold value is subject to variation of the channel skew speci

cations.
Table 9: TLA5000 MagniVu feature
Characteristic
Description
MagniVu memory depth
16,000 samples per channel
MagniVu sampling period
Data is asynchronously sampled and stored every 125 ps in a separate
high resolution memory. The storage speed may be changed (by software)
to 250 ps, 500 ps, or 1000 ps so that MagniVu memory covers more time
at a lower resolution.
Table 10: TLA5000 Data Placement
Characteristic
Description
System time zero placement error
(Typical)
±4 ns + backplane 10 MHz skew
All stored data is referenced to this point.
Data correlation error
(Typical)
±200 ps + system time zero placement error
