Usage
:TRACe:POINts <newSize>
:TRACe:POINts <newSize>, "<bufferName>"
:TRACe:POINts?
:TRACe:POINts? "<bufferName>"
<newSize>
The new size for the buffer
<bufferName>
A string that indicates the reading buffer; the default buffers (defbuffer1 or
defbuffer2) or the name of a user-defined buffer; if no buffer is specified,
defbuffer1 is used
Details
This command allows you to change or view how many readings a buffer can store. Changing the
size of a buffer will cause any existing data in the buffer to be lost.
The overall capacity of all buffers stored in the instrument cannot exceed 6,875,000 readings for
standard reading buffers and 27,500,000 for compact reading buffers. For more information about
buffer capacity, see Setting reading buffer capacity (on page 3-8).
Example
TRACe:MAKE "testData", 100
TRACe:POINts 300, "testData"
TRACe:POINts? "testData"
TRACe:POINts?
Create a user-defined reading buffer named
testData with a capacity of 100
measurements.
Change the buffer capacity to 300.
Query the capacity of testData.
Output:
300
Query the capacity of the default buffer.
Output:
10000
