______________________________
Time-Qualified T riggers on the exiting
Pattern edge of a pattern which
meets the user-specified duration criterion.
Greater than, less than,
or within range duration criterion can be
used. Duration range is
20 ns to 160 ns. Recovery time after valid patterns with invalid duration is <12 ns.
Events Delay Triggers on the nth
edge or pattern as
specified by the user .
Time-qualification is
applied only to the 1st
of n patterns.
______________________________
Auto-T rigger Self-triggers if no trig-
ger condition is found
~ 50 ms after arming.

Measurement Functions
______________________________
Time Markers Two markers (x and o)
measure time intervals
manually, or automatically with statistics.
______________________________
Voltage Two markers (a and b)
Markers measure voltage and
voltage differences.
______________________________
Automatic Period, frequency,
Measurementsrise time, fall time,
+width, –width, peakto-peak voltage, overshoot, and undershoot.

Trigger Modes
Immediate Triggers immediately
after arming condition is
met. (Arming condition
is Run, Group Run,
cross arming signal, or
Port In BNC signal).
Edge Triggers on rising or
falling edge from channel 1 or 2.
Pattern Triggers on entering or
exiting logical pattern
specified across channels 1 or 2. Each channel can be specified as
high (H), low (L), or don't
care (X) with respect to
the level settings in the
edge trigger menu.
Patterns must be
>1.75 ns in duration to
be recognized.

Specifications and
Characteristics [1]
[7] Upper bandwidth reduces by 2.5 MHz for every
degree C above 35°C.
[8] Rise time calculated as tr =
0.35
bandwidth
[9] Vertical gain accuracy decreases 0.08% per
degree C from software calibration temperature.
[10] Specification applies at the maximum sampling
rate. At lower rates, replace 150 ps in the formula
with ( 0.15 × sample interval) where sample interval is defined as 1/sample rate.
