3-2-3. :ACQuire<X>:MEMory?
Query
Description
Returns the data in acquisition memory for the
selected channel as a header + raw data.
Syntax
:ACQuire<X>:MEMory?
Related Commands
ACQuire:RECOrdlength
:HEADer
Parameter
<X>
Channel number (1 to 4)
Return parameter
Returns acquisition settings followed by raw waveform
block data.
<string>
Returns the acquisition settings for the selected
channel.
Format:
parameter(1),setting(1);parameter(2),setting(2)…para
meter(n),setting(n);Waveform Data;
<waveform block data>
Header followed by the raw waveform data.
Format:
Header: The header (in ASCII) encodes the number of
bytes for the header followed by the number of data
points in bytes for the raw data.
#42000
Header identifier
Indicates the number
of characters that will
encode the number of
data points (ie. 2000
= 4 characters) after
which the raw data
will follow.
Indicates the number
of bytes that follow
(for the raw data).
ASCII
Raw Data:
Each two bytes (in hex) encodes the vertical data of a
data point. The data is signed hex data (2’s
complement, -32768 ~ 32767).
Waveform Raw Data Example:
Header raw data……….
Hex:
23 34 32 30 30 30 00 1C 00 1B 00 1A 00 1A 00 1B
18
………..
ASCII/Decimal:
#42000 28 27 26 26 27…….
The actual value of a data point can be calculated with
the following formula:
(Decimal value of hex data/AD Factor) * vertical scale.
Note: AD Factor is fixed as 25. The vertical scale is
returned with the acquisition settings that precede the
raw data.
For example if the raw data for a point is 001C (=28
decimal) then,
(28/25) x 0.5 = 0.56V
