Horizontal
Time base range 0.5 ns/div to 5 s/div
Time interval measurement accuracy [7] [8] ± [(0.005% of ∆t) + (2x10 -6 x delay setting) + 150 ps]
Oscilloscope Triggering
Trigger level range Bounded within channel display window
Trigger sensitivity [8] dc to 50 MHz: 0.063 x Full Scale
50 MHz to 500 MHz: 0.125 x Full Scale
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.
Time-qualified pattern Triggers on the exiting edge of a pattern that 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-trigger Self-triggers if no trigger 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 markers Two markers (a and b) measure voltage and voltage
differences.
Automatic measurements Period, frequency, rise time, fall time, +width, –width,
peak-to-peak voltage, overshoot, and undershoot.
[4] Upper bandwidth reduces by 2.5 MHz for every degree C above 35°C.
[5] Rise time calculated as t
r
= 0.35
bandwidth
[6] Vertical gain accuracy decreases 0.08% per degree C from software calibration temperature.
[7] Specification applies at the maximum sam-pling rate. At lower rates, replace 150 ps in the formula with ( 0.15 x sample
interval) where sample interval is defined as 1/sample rate.
[8] Specifications valid within ± 10°C of auto-calibration temperature.
