6: Reading buffers 2470 High Voltage SourceMeter Instrument
6-14 2470-901-01 Rev. A / May 2019
Using SCPI commands to set the buffer fill mode:
To set the testData reading buffer fill mode to continuous, send the following command:
TRACe:FILL:MODE CONT, "testData"
To set the defbuffer1 reading buffer fill mode to fill once, send the following command:
TRACe:FILL:MODE ONCE, "defbuffer1"
To get the fill mode that is set, send the following command:
TRACe:FILL:MODE? "defbuffer1"
Where a return of ONCE indicates the buffer is set to fill once and a return of CONT indicates the buffer
is set to fill continuously.
Using TSP commands to set a buffer fill mode:
To set the testData reading buffer fill mode to continuous, send the following command:
testData.fillmode = buffer.FILL_CONTINUOUS
To set the defbuffer1 reading buffer fill mode to fill once, send the following command:
defbuffer1.fillmode = buffer.FILL_ONCE
To print the defbuffer1 fill mode setting, send the following command:
print(defbuffer1.fillmode)
Where a return of 0 indicates the buffer is set to fill once and a return of 1 indicates the buffer is set to
f
ill continuously.
Selecting a buffer
The default reading buffer is defbuffer1. You can also use a different buffer (defbuffer2 or a
u
ser-defined reading buffer).
When you use remote commands to create buffers, the buffers are available to the system and can
be used with any command that takes a buffer parameter. A newly created buffer automatically
becomes the active buffer. If the active buffer is deleted, defbuffer1 becomes the active buffer.
