Performance Characteristics
Agilent 54640-series Performance Characteristics
Trigger System
Sources: 54641A/42A: Ch 1, 2, line, ext
54641D/42D: Ch 1, 2, line, ext, D15 - D0
Modes Auto, Triggered (normal), Single
Holdoff Time ~60 ns to 10 seconds
Selections Edge, Pattern, Pulse Width, CAN, Duration, I2C, Se quence, 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 t han, greater than, or within a
specified range on any of the source channels.
Minimum pulse width setting: 2 ns
Maximum pulse width setting: 10 s
CAN Trigger on CAN (Controller Area Network) version 2.0A and 2.0B signals. It can trig ger
on the Start of Frame bit of a data frame, a remote transfer request fr ame, 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 s tart/stop condition, a restart, a missing
acknowledge, or user defined frame with address and/or data values. Al so trigger on
Missing Acknowledge, Restart, EEPROM read, and 10-bit write.
Sequence Find event A, trigger on event B, with opt ion 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 Sel ect framing ad well as c lock 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 d ata lines. USB low speed and
high speed are supported.
TV Trigger on an y analog channel for NTSC, PAL, PAL-M, or SE CAM broadcast standards
on either positive or negative composite video signals. Modes su pported include Field
1, Field 2, or both, all lines, or any line within a field. Also supports triggering on
non-interlaced fields. TV trigger sensitivit y: 0.5 division of synch signal.
Autoscale Finds and displays all active analog an d digital channels (for 54641D /54642D), sets edge
trigger mode on highest numbered channel, sets vertical sensitivity on analog
channels and thresholds on digital channels, time base to di splay ~1.8 periods.
Requires minimum voltage >10mVpp, 0.5% duty cycle and minimum frequency >50Hz.
* Denotes Warranted Specifications, all others are typical. Specifications are valid after a 30-minute warm-up period and
±10 °C from firmware calibration temperature.
