Infiniium Performance Characteristics (continued)
Software trigger (InfiniiScan event identification software (Option 009))
Trigger modes
Generic serial Software triggers on NRZ-encoded data up to 80-bit pattern. Supports multiple clock data
recovery methods including constant frequency, 1st order PLL, 2nd order PLL, explicit clock,
explicit 1st order PLL, 2nd order PLL (requires N5384A except for the constant frequency).
Measurements Software triggers on the results of the measurement values. For example, when the “pulse
width” measurement is turned on, InfiniiScan measurement software triggers on a glitch as
narrow as 250 ps.
Non-monotonic Software triggers on the non-monotonic edge. The non-monotonic edge is specified by
setting a hysteresis value.
Runt Software triggers on a pulse that crosses one threshold but fails to cross a second
threshold before crossing the first again.
Zone qualify 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.
Trigger: Digital channels MSO8064A, MSO8104A
Threshold range (user defined) ± 8.0 V in 10-mV increments
Threshold accuracy
1
± (100 mV + 3% of threshold setting)
Predefined thresholds TTL=1.4 V, 5.0 V CMOS=2.5 V, 3.3 V CMOS=1.65 V, 2.5 V CMOS=1.25 V, ECL=–1.3 V,
PECL=3.7 V
1. Denotes warranted specifications, all others are typical. Specifications are valid after a 30-minute warm-up period and ±10 °C from
firmware calibration temperature.
