Part 6: IEEE 488.2 Command Reference
MEMORY_SIZE, MSIZ
Description
On most models where this command/query is available, MEMORY_SIZE allows selection of the memory
length used for acquisition. Refer to the product datasheet at teledynelecroy.com for maximum memory
specifications.
The MEMORY_SIZE? query returns the current maximum memory length used to capture waveforms.
Command Syntax
MEMORY_SIZE <size>
<size>:= <500, 1e+3, …, 2.5e+6, 5e+6, 1e+7, etc.>
Or, alternatively:
<size>: = <500, 1000, 2500, 5000, 10K, 25K, 50K, 100K, 250K, 500K, 1MA, 2.5MA, 5MA,
10MA, 25MA, etc.>
Values other than those listed here are recognized by the oscilloscope as numeric data. For example, the
oscilloscope recognizes 1.0M as 1 millisample. However, it recognizes 1MA as 1 megasample.
Note: The oscilloscope adapts to the closest valid memory size according to available channel
memory. Reducing the number of data points results in faster throughput.
Query Syntax
MSIZ?
Response Format
MEMORY_SIZE <size>
Example (GPIB)
The following instruction sets the oscilloscope to acquire at most 10,000 data samples per single-shot or
RIS acquisition:
CMD$="MSIZ 10K": CALL IBWRT(SCOPE%,CMD$)
CMD$="MSIZ 10e+3": CALL IBWRT(SCOPE%,CMD$)
