Specifications 3-3
3.5 Smart Trigger Types
Pattern : Trigger on the logic combination of 5 inputs - CH1, CH2, CH3, CH4 and
EXT Trigger, where each source can be defined as High, Low or Don't Care.
The Trigger can be defined as the beginning or end of the specified pattern
Signal or Pattern Width : Trigger on glitches as short as 600 ps or on pulse widths
Within/outside two limits selectable from 600 ps to 20 s.
Slew Rate : Trigger on rising, falling edges within/outside two time limits selectable
from 600 ps to 20 s.
Signal or Pattern Interval : Trigger on an interval between two limits selectable
from 2ns to 20s.
Dropout : Trigger if the signal drops out for longer than a time-out from 2 ns to 20s.
Runt
: Trigger on positive or negative Runts within/outside two limits selectable
from 600 ps to 20 s.
State/Edge Qualified : Trigger on any source only if a given state (or transition) has
occurred on another source. The delay between these events can be defined as a
number of events on the trigger channel or as a time interval.
TV : Allows selection of up to 1500 lines and field synchronization for PAL,
SECAM, NTSC or non-standard video
Exclusion Triggering : Trigger on intermittent faults by specifying the normal width,
period, risetime or amplitude of a signal.
The oscilloscope will trigger only on aberrations.
3.6 Autosetup
Automatically sets sensitivity, vertical offset and timebase on all display channels.
Autosetup Time : Approximately 3 seconds.
Vertical Find : Automatically sets sensitivity and offset for selected channel.
3.7 Probes
Model : One PP005 probe is supplied per channel. DC to 500 MHz typical at
probe tip, 500 V max.
Optional Probes : 2.5 Ghz FET probe AP022, 1 GHz FET probe (AP020); 1 GHz
active differential probe (AP034), 500 MHz active differential probe (AP033).
Probe calibration : Max 1 V into 1 M

programmable, pulse or square wave selectable, rise and fall time 1 ns typical.
Alternatively, the Calibrator output can provide a trigger output or a Pass/Fail test
output.
