Details
When a reading buffer is set to fill once, no data is overwritten in the buffer. When the buffer is filled,
no more data is stored in that buffer and new readings are discarded.
When a reading buffer is set to fill continuously, the oldest data is overwritten by the newest data after
the buffer fills.
When you change the fill mode of a buffer, any data in the buffer is cleared.
Example
TRACe:MAKE "testData", 100
TRACe:FILL:MODE? "testData"
TRACe:FILL:MODE CONT, "testData"
TRACe:FILL:MODE? "testData"
TRACe:FILL:MODE?
Create a user-defined reading buffer named
testData
with a capacity of 100 measurements.
Query the fill mode setting for
testData
.
Output:
ONCE
Set
testData
fill mode to continuous.
Query the fill mode setting for
testData
.
Output:
CONT
Query the fill mode setting for
defbuffer1
.
