Digital Delta-t Accuracy
(non-Vernier settings)
54621A/D, 54622A/D, 54624A:
Same Channel: ± 0.01ꢂ reading ± 0.1ꢂ screen width ± (1 digital sample period, 2.5 or 5 ns
based on sample rate of 200/400 MSa/s)
Channel-to-Channel: ± 0.01ꢂ reading ± 0.1ꢂ screen width ± (1 digital sample period, 2.5 or 5 ns)
± chan-to-chan skew (2 ns typical, 3 ns maximum)
54641A/D, 54642A/D:
Same Channel: ± 0.005ꢂ reading ± 0.1ꢂ screen width ± (1 digital sample period, 1ns)
Channel-to-Channel: ± 0.005ꢂ reading ± 0.1ꢂ screen width ± (1 digital sample period) ± chan-to-chan skew
Same Channel Example (54641A/D, 54642A/D):
for signal with pulse width of 10 µs, scope set to 5 µs/div (50 µs screen width),
delta-t accuracy = ± ±.005ꢂ(10 µs) + 0.1ꢂ(50 µs) + 1 ns} = 51.5 ns

Holdoff Time
Selections
Edge
2
Edge, Pulse Width, Pattern, TV, Duration, Sequence, CAN, LIN, USB, I C, SPI
Trigger on a rising or falling edge of any source
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 s
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.
Sequence
CAN
Arm on event A, trigger on event B, with option to reset on event C or time delay.
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.
LIN
Trigger on LIN (Local Interconnect Networking) sync break at beginning of message 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 full speed are supported.
