Digital Delta-t Accuracy (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)

Example:

for signal with pulse

width of 10 µs, scope set to

5 µs/div (50 µs screen width), and

single pod active (400 MSa/s),

delta-t accuracy= ±{.01%(10 µs) +

0.1% (50 µs) + 2.5 ns} = 53.5 ns

Channel-to-Channel

± 0.01% reading ± 0.2% screen

width ± (1 logic sample period,

2.5 or 5 ns) ± chan-to-chan skew

(2 ns typical, 3 ns maximum)

Modes

Auto, Auto level, Triggered

(normal), Single

Holdoff Time

~60 ns to 10 seconds

Selections

Edge, Pattern, Pulse Width, TV,

Sequence, I

C, Duration

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

Trigger on any scope 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

Find event A, trigger on event B,

with option to reset on event C or

time delay.

Trigger on I

C (Inter-IC bus) serial

protocol at a start/stop condition or

user defined frame with address

and/or data values.

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

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.
