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
CAUTION:
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.
