General Information

Trigger System

*Denotes Warranted Specifications, all others are typical. Specifications are valid after a 30-minute warm-up period and ±10 °C from firmware calibration temperature.

Trigger System

Sources:	54621A/22A: Ch 1, 2, line, ext
	54621D/22D: Ch 1, 2, line, ext, D15 - D0
	54624A: Ch 1, 2, 3, 4, line, ext
Modes	Auto, Auto level, Triggered (normal), Single
Holdoff Time	~60 ns to 10 seconds
Selections	Edge, Pattern, Pulse Width, CAN, Duration, I2C, Sequence, SPI, TV, USB
Edge	Trigger on a rising or falling edge of any source.
Pattern	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.
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: 5 ns
	Maximum pulse width setting: 10 s
CAN	Trigger on CAN (Controller Area Network) version 2.0A and 2.0B signals. It can trigger
	on the Start of Frame bit of a data frame, a remote transfer request frame, or an overload
	frame.
Duration	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
I2C	Trigger on I2C (Inter-IC bus) serial protocol at a start/stop condition, a restart, a missing
	acknowledge, or user defined frame with address and/or data values. Also trigger on
	Missing Acknowledge, Restart, EEPROM read, and 10-bit write.
LIN	Trigger on LIN (Local Interconnect Network) sync break at beginning of message frame.
Sequence	Find event A, trigger on event B, with option to reset on event C or time delay.
SPI	Trigger on SPI (Serial Peripheral Interface) a data pattern during a specific framing
	period. Support positive and negative Chip Select framing ad well as clock Idle framing
	and user-specified number of bits per frame.
USB	Trigger on USB (Universal Serial Bus) Start of Packet, End of Packet, Reset Complete,
	Enter Suspend, or Exit Suspend on the differential USB data lines. USB low speed and
	high speed are supported.
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 non-
	interlaced fields. TV trigger sensitivity: 0.5 division of synch signal.
Autoscale	Finds and displays all active analog and digital (for 54621D/54622D) channels, sets edge
	trigger mode on highest numbered channel, sets vertical sensitivity on analog channels
	and thresholds on digital channels, time base to display ~1.8 periods. Requires minimum
	voltage >10 mVpp, 0.5% duty cycle and minimum frequency >50 Hz.
