6. Press the Acquire key.

Acquire

7. Press

Normal

8. Press

Peak-Detect

and see

that a spike noise is

captured.

Peak

Detect

Example

The peak detect mode reveals the occasional glitch.

Normal mode

Peak detect mode

Real time vs Equivalent time sampling mode

Backgrounds

The oscilloscope automatically switches between

two sampling modes, Real-time and Equivalent-

time, according to the number of active channels

and sampling rate.

Real-time
sampling

One sampled data is used to reconstruct a single

waveform. Short-time events might get lost if the

sampling rate gets too high. This mode is used

when the sampling rate is relatively low

(250MSa/s or lower).

Equivalent-time
sampling

Multiple numbers of sampled data are

accumulated to reconstruct a single waveform.

Restores greater waveform details but takes longer

to update the waveform. This mode is used when

the sampling rate becomes higher than 250MSa/s.

The maximum equivalent-time sampling rate is

25GSa/s.

Display

The Display section describes how to configure the display settings:

drawing type, waveform accumulation, contrast adjustment, and

grid settings.

Selecting the vector or dot drawing

1. Press the Display key.

Display

Procedure

2. Press

Type

repeatedly to

select the waveform

drawing.

Types

Dots

Only the sampled dots are displayed.

Vectors

The sampled dots are connected by

lines.

Accumulating the waveform

Background

Accumulation preserves the old waveform

drawings and overwrites new waveforms on top

of it. It is useful for observing waveform variation.

1. Press the Display key.

Procedure

2. Press

Accumulate

to turn on

the waveform accumulation.

3. To clear the accumulation

and start it over (refresh),
