Trigger on a rising or falling edge of any source.
Trigger on a pattern of high, low, and don't care levels and a rising or falling edge
established across any of the sources. The analog channel's high or low level is
defined by that channel's trigger level.
Trigger when a positive- or negative-going pulse is less than, greater than, or within a
specified range on any of the source channels.
Minimum pulse width setting: 5 ns
Maximum pulse width setting: 10 s
Trigger on any scope channel for NTSC, PAL, PAL-M, or SECAM broadcast standards
on either positive or negative composite video signals. Modes supported include Field
1, Field 2, or both, all lines, or any line within a field. Also supports triggering on non-
interlaced fields. TV trigger sensitivity: 0.5 division of synch signal.
Find event A, trigger on event B, with option to reset on event C or time delay.
2
Trigger on I C (Inter-IC bus) serial protocol at a start/stop condition or user defined
frame with address and/or data values.
Trigger on a multi-channel pattern whose time duration is less than a value, greater
than a value, greater than a time value with a timeout value, or inside or outside of a
set of time values.
Minimum duration setting: 5 ns
Maximum duration setting: 10 s
Finds and displays all active scope and logic channels (for 54621D/54622D), sets edge
trigger mode on highest numbered channel, sets vertical sensitivity on scopes
channels and thresholds on logic channels, time base to display ~1.8 periods. Requires
minimum voltage >10 mVpp, 0.5% duty cycle and minimum frequency >50 Hz.
