In-Depth Information
• Pattern
Trigger on a pattern of high, low, and don't care levels and/or 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.)
• Pulse width
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: 5ns (2 ns on 54641A/D, 54642A/D
analog channels)
Maximum pulse width setting: 10 sec.
•TV
Trigger on any analog 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
noninterlaced fields. TV trigger sensitivity: 0.5 division of synch
signal.)
• Sequence
Arm on event A, trigger on event B, with option to reset on event
C or time delay.
• CAN
Trigger on CAN (Controller Area Network) version 2.0A and 2.0B
signals; can trigger on the start of frame bit of a data frame, a
remote transfer request frame, or an overload frame.
• LIN
Trigger on LIN (Local Interconnect Networking) sync break at be-
ginning of message frame.
• USB
Trigger on USB (Universal Serial Bus) start of packet, end of packet,
reset complete, enter suspend, or exit uspend on the differential
USB data lines. USB low speed and full speed are supported.
•
2
C
Trigger on I
2
C (Inter-IC bus) serial protocol at a start/stop condition
or user-defined frame with address and/or data values. Also
trigger on missing acknowledge, restart, EEPROM read, and
10-bit write.
• SPI
Trigger on SPI (Serial Protocol Interface) data pattern during a spe-
cific framing period. Support positive and negative chip select
framing as well as clock idle framing and user-specified number
of bits per frame.
