Characteristics
Trigger
Sources All four input plug-in slots can be used for triggering. See
plug-in specifications for more details.
Edge Slope Positive/negative
Holdoff Range 60 ns to 320 ms
Pattern Trigger A pattern can be specified using any channel or
external trigger input (up to four bits wide). Each of the inputs can be
specified as high, low, or don't care with respect to the trigger level
setting for that source. Trigger occurs when that pattern is entered or
exited.
Glitch Trigger This mode makes it easy to look for glitches on a single
source. The user can distinguish glitches down to 3 ns ±1 ns in width
and can capture glitches as narrow as 500 ps in width, depending on the
plug-in.
Time-Qualified Pattern Trigger A trigger will occur on the first edge
to exit a pattern only if it meets one of these criteria: pattern present
<[time], pattern present >[time], pattern present in range >[time1] and
<[time2]. The time settings are adjustable from 20 ns to 160 ms [±(3% +
2 ns)] with 10 ns resolution. Filter recovery time is ≤12 ns.
State Trigger A pattern is specified on any three of the four inputs,
with the fourth input used as a clock. Trigger occurs on the rising or
falling edge of the input specified as the clock, and when the pattern is
present or is not present. Setup time for the pattern with respect to the
clock is 10 ns or less; hold time is zero.
Event-Delayed Trigger The trigger is qualified by an edge. The delay
can be spec- ified as a number of occurrences of a rising or falling edge of
any input. After the delay, an occurrence of a rising or falling edge of any
input will generate the trigger. The trigger occurrence value is selectable
from 1 to 16,000,000. The maximum edge counting rate is 70 MHz.
Edges occurring <30 ns after the qualifying edge may not be detected.
Time-Delayed Trigger The trigger is qualified by an edge. The delay
is selectable from 30 ns to 160 ms. After the delay, an occurrence of a
rising or falling edge on any one selected input will generate the trigger.
Standard and User Defined TV Trigger You can trigger on 525
lines/60 Hz, 625 lines/50 Hz, and 875 lines/60 Hz standard TV systems, or
you can use the user defined menu to customize the TV triggering.
