memory for long memory.

Syntax

< Long >

< Short >

:acquire:lmemory?

:acq:lmem?

Parameter

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 the use of 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
can be returned. If only
CH1 is active then up to
2M points can be
returned.

Data format

Six data elements are concatenated to form one
data string.
