bufferVar.capacity
This attribute contains the number of readings a buffer can store.
Type TSP-Link accessible Affected by Where saved Default value
Attribute (R/W) Yes Restore configuration
Instrument reset
Power cycle
Not applicable Not applicable
Usage
bufferCapacity = bufferVar .capacity
bufferVar .capacity = bufferCapacity
bufferCapacity
The maximum number of readings the buffer can store
bufferVar
The name of the reading buffer, which may be a default buffer (
defbuffer1
or
defbuffer2
) or a user-defined buffer
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
reset()
testData = buffer.make(500)
capTest = buffer.make(300)
bufferCapacity = capTest.capacity
print(bufferCapacity)
print(testData.capacity)
testData.capacity = 600
print(testData.capacity)
print(defbuffer1.capacity)
Create two user-defined reading buffers:
testData
and
capTest
.
Create a variable called
bufferCapacity
to hold the
capacity of the
capTest
buffer.
Print
bufferCapacity
.
Output:
300
Print the capacity of
testData
.
Output:
500
Changes the capacity of
testData
to 600.
Print the capacity of
testData
.
Output:
600
Print the capacity of the default buffer
defbuffer1
.
Output:
10000
