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, this parameter defaults to
defbuffer1
Details
This command determines if a reading buffer is filled continuously or is filled once and stops.
Use this command to read the fill mode of the specified reading buffer.
Use this command to set the fill mode of the specified reading buffer.
When a reading buffer is set to
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
ONCE
, the first new measurement is stored at
n
+1
, where
n
is the number of
readings stored in the buffer.
When a reading buffer is set to
CONTinuous
, the oldest data is overwritten by the newest data after the buffer
fills.
You can only change the fill mode of an empty reading buffer. Use
TRACe:CLEar
to empty the buffer.
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:
testData
, with the
capacity for 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
.
Output:
CONT
