Holdoff Time ~60 ns to 10 seconds
Selections Edge, Pattern, Pulse Width, CAN, Duration, I

C, 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

C Trigger on I

C (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.
Sequence Find event A, trigger on event B, with option to reset on event C or time delay.
SPI Trigger on SPI (Serial Protocol 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 channels (for 54621D/54622D), 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.
* Denotes Warranted Specifications, all others are typical. Specifications are valid after a 30-minute warm-up period and
±10 °C from firmware calibration temperature.
