Performance characteristics
Hardware trigger (continued)
Trigger modes (continued)
Window
Video
Triggers on an event associated with a window defined by two-user adjustable thresholds. Event can
be window “entered,” “exited,” “inside (time qualified),” or “outside (time qualified)” voltage range.
Trigger point can be “cross window boundary” or “time out.” Time qualify range: from 250 ps to 10 s.
Triggers from negative sync composite video, field 1, field 2, or alternating fields for interlaced
systems, any field, specific line, or any line for interlaced or non-interlaced systems. Supports
NTSC, PAL-M (525/60), PAL, SECAM (625/50), EDTV (480p/60), EDTV (576p/50), HDTV (720p/60),
HDTV (720p/50), HDTV (1080i/60), HDTV (1080i/50), HDTV (1080p/60), HDTV (1080p/50), HDTV
(1080p/30), HDTV (1080p/25), HDTV (1080p/24), and user-defined formats.
Trigger sequences Three stage trigger sequences including two-stage hardware (Find event (A) and Trigger event (B))
and one-stage InfiniiScan software trigger. Supports all hardware trigger modes except “edge then
edge” and “video,” and all InfiniiScan software trigger modes. Supports “delay (by time)” and “reset
(by time or event)” between two hardware sequences. The minimum latency between “find event
(A)” and “trigger event (B)” is 3 ns.
Trigger qualification AND qualifier Single or multiple channels may be logically qualified with any other trigger mode
Trigger holdoff range 100 ns to 10 s
Trigger actions Specify an action to occur and the frequency of the action when a trigger condition occurs. Actions
include e-mail on trigger and execute “multipurpose” user setting.
Trigger shortcuts Provides easy shortcuts to all trigger features
Software trigger (requires InfiniiScan event identification software – Option 009)
Trigger modes
Generic serial
Measurement limit
Non-monotonic edge
Runt
Zone qualify
Software triggers on NRZ-encoded data up to 8.0 Gbps, up to 80-bit pattern. Support multiple clock
data recovery methods including constant frequency, 1st-order PLL, 2nd-order PLL, explicit clock,
explicit 1st-order PLL, explicit 2nd-order PLL, Fibre Channel, FlexRay receiver, FlexRay transmitter
(requires E2688A except for the constant frequency clock data recovery mode).
Software triggers on the results of the measurement values. For example, when the “pulse width”
measurement is turned on, InfiniiScan measurement software trigger triggers on a glitch as narrow
as 75 ps. When the “time interval error (TIE)” is measured, InfiniiScan can trigger on a specific TIE
value.
Software triggers on the non-monotonic edge. The non-monotonic edge is specified by setting a
hysteresis value.
Software triggers on a pulse that crosses one threshold but fails to cross a second threshold before
crossing the first again. Unlike hardware runt trigger, InfiniiScan runt trigger can be further qualified
via a hysteresis value.
Software triggers on the user defined zones on screen. Zones can be specified as either “must
intersect” or “must not intersect.” Up to four zones can be defined.
