:TRACe:FILL:MODE
This command determines if a reading buffer is filled continuously or is filled once and stops.
Type Affected by Where saved Default value
Instrument reset
defbuffer2: CONT
User-defined buffers: ONCE
Usage
:TRACe:FILL:MODE <fillType>
:TRACe:FILL:MODE <fillType>, "<bufferName>"
:TRACe:FILL:MODE?
:TRACe:FILL:MODE? "<bufferName>"
Fill the buffer continuously: CONTinuous
Fill the buffer, then stop:
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
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.
