Data Sheet
Trigger Modes
Mode Description
Edge Positive or negative slope on any channel or front-panel
auxiliary input. Coupling includes DC, AC, HF reject, LF
reject, and noise reject
Glitch Trigger on or reject glitches of positive, negative, or
either polarity. Programmable glitch width is 4 ns
minimum to 8 s maximum
Runt Trigger on a pulse that crosses one threshold but fails to
cross a second threshold before crossing the first again
Width Trigger on width of positive or negative pulse either
within or outside of selectable limits (4 ns to 8 s)
Timeout Trigger on an event which remains high, low, or either, for
aspecified time period (4 ns to 8 s)
Transition Trigger on pulse edge rates that are faster or slower than
specified. Slope may be positive, negative, or either
Setup/Hold Trigger on violations of both setup time and hold time
between clock and data present on any two input
channels
Pattern Trigger when any logical pattern of signals goes false
or stays true for specified period of time (4 ns to 1 s).
Pattern (AND, OR, NAND, NOR) specified for all analog
and digital input channels defined as High, Low, or Don’t
Care
State Any logical pattern of analog channels and digital
channels (MSO models) clocked by edge on another
channel. Trigger on rising or falling clock edge
Video Trigger on all lines, specific line number, odd, even,
or all fields on NTSC, PAL, SECAM, and HDTV

IN, SETUP; Address can be specified for Any, OUT,
IN, and SETUP token types. Address can be further
specified to trigger on ≤,<,=,>,≥, != a particular
value, or inside or outside of a range. Frame number
can be specified for SOF token using Binary, Hex,
Unsigned Decimal, and Don’t Care digits.
Data Packet Trigger – Any data type, DATA0, DATA1;
Data can be further specified to trigger on ≤,<,=,>,
