Table 2 -3: Trigger specifications (cont.)
Characteristic Description
Trigger Coupling Typical Sensitivity
AC Coupling 1 div for frequencies above 45 Hz.
Attenuates signals below 45 Hz.
NOISE REJ 2.5 times the DC-coupled limits
HF REJ
1.0 times the DC-coupled limit from DC to 50 kHz.
Attenuates signals above 50 kHz
Edge-type trigger sensitivity, not DC
coupled, typical
LF REJ
1.5 times the DC-coupled limits for frequencies above
50 kHz. Attenuates signals below 50 kHz
Video-type trigger formats and field
rates
Triggers from negative sync composite video, field 1 or field 2 for interlaced systems, on any
field, specific line, or any line for interlaced or non-interlaced systems. Supported s ystems
include NTSC, PAL, and SECAM.
Delayed and main trigger
Source Sensitivity
Any input channel
0.6 to 2.5 divisions of video sync tip
Video-type trigger sensitivity, typical
Aux In (External) Video not supported through Aux In (External) input
Lowest frequency for successful
operation of "Set Level to 50%"
function, typical
45 Hz
Logic-type or logic qualified trigger
or events-delay sensitivities, DC
coupled, typical
1.0 division from DC to maximum bandwidth
Pulse-type runt trigger sensitivities,
typical
1.0 division from DC to maximum bandwidth
Pulse-type trigger width and glitch
sensitivities, typical
1.0 division
For all vertical settings, the minimums are:
Trigger type Pulse width Re-arm
time
Time
between
channels
Logic Not applicable 2 ns 1 ns
Time Qualified Logic
4ns 2ns 1ns
Logic-type triggering, minimum logic
or rearm time, typical
For logic, time between channels refers to the length of time a logic state derived from more
than one channel must exist to be recognized. Fo r events, the time is the minimum time
between a main and delayed event that will be recognized if more than one channel is used.
For all vertical settings
Clock active Clock inactive
User hold time + 2.5 ns 2 ns
Minimum c lock pulse widths for
setup/hold time violation trigger,
typical
An active pulse width is the width of the clock pulse from its active edge to its inactive edge.
An inactive pulse width is the width of the pulse from its inactive edge to its active edge.
The U ser hold time is the number selected by the user.
