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, I2C, 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.
