COMMAND DETAILS

:ACQuire<X>:LMEMory

Query

Description

Returns the total waveform data in the acquisition

memory for long memory.

Syntax

< Long > < Short >

:acquire<X>:lmemory? :acq<X>:lmem?

Parameter

<X>

Channel

1/2

Channel1/2

Note

Please note that the number of points is limited to

4000 when the scope is running.

You can get the full memory depth when the

“Single” key is pressed with a triggered signal.

You can also get the full memory depth when the

“STOP” key is pressed,

However, the long memory may not fully fill up if

a slow time base is used with a fast sample rate

Also note that there are several time base settings

that don’t result in 100% of available memory, due

to a limited number of available sample rates.

Example :acquire1:lmemory?

Returns the channel 1

long memory waveform

data

If both channels are

active up to 1M points

are returned. If only CH1

is active then up to 2M

points are returned.

Data format

Six data elements are concatenated to form one

data string.

A B C D E F

A: Data size digit B: Data size

C: Time interval D: Channel indicator

E: Reserved data F: Waveform data

Data size digit

Indicates the number of digits used for the data

string that follows. The data size digit is 4 for 4000

points, 7 for 1M or 2M points.

Data size

Indicates the data size. The data size varies from

8008 (4000 points), 2000008 (1M points) or 4000008

(2M points).

Time interval

Indicates the time interval between two adjacent

sampling points in the floating point format,

compatible with IEEE 754 standards.

Note: The data is sorted in the little-endian format.

Channel indicator

Indicates the channel, 1 or 2.

Reserved data

An unused data block, 3 bytes.

aveform data

The waveform data comprised of 2M data points.

Each point is made up of 2 bytes (16 bits), high

byte (MSB) first.
