Performance Characteristics
(continued)
Horizontal (continued)
Digital Delta-t Accuracy 54621A/D, 54622A/D, 54624A:
(non-Vernier settings) Same Channel: ±0.01% reading ±0.1% screen width ±(1 digital sample period, 2.5 or 5 ns
based on sample rate of 200/400 MSa/s)
Channel-to-Channel: ±0.01% reading ±0.1% 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: ±0.005% reading ±0.1% screen width ±(1 digital sample period, 1ns)
Channel-to-Channel: ±0.005% reading ±0.1% 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 = ±{.005%(10 µs) + 0.1%(50 µs) + 1 ns} = 51.5 ns
Delay Jitter <1 ppm
RMS Jitter 0.025% screen width + 30 ps
Modes Main, Delayed, Roll, XY
XY Bandwidth: Max bandwidth
Phase error @ 1 MHz: 1.8 degrees
Z Blanking: 1.4 V blanks trace (use external trigger) - 54621A/D, 54622A/D, 54624A only
Trigger System
Sources: 54621A/622A, 54641A/642A: Ch 1, 2, line, ext
54621D/622D, 54641D/642D: Ch 1, 2, line, ext, D15 - D0
54624A: Ch 1, 2, 3, 4, line, ext
Modes Auto, Triggered (normal), SingleAuto level (54621A/D, 54622A/D, 54624A only)
Holdoff Time ~60 ns to 10 seconds
Selections Edge, Pulse Width, Pattern, TV, Duration, Sequence, CAN, LIN, USB, I 2 C, SPI
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/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 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. 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.
* Denotes Warranted Specifications, all others are typical. Specifications are valid after a 30-minute warm-up period and ±10 °C from firmware calibration temperature.
