Storing data in buffers
Using SCPI commands:
The table below lists the SCPI commands that you use for data storage.
Command Description
:TRACe:ACTual? This command contains the number of readings in the specified
buffer. See
:TRACe:ACTual? (on page 12-117) for more information.
:TRACe:ACTual:END? This command returns the last index in a reading buffer. See
:TRACe:ACTual:END? (on page 12-118) for more information.
:TRACe:ACTual:STARt? This command returns the starting index in a reading buffer. See
:TRACe:ACTual:STARt? (on page 12-119) for more information.
:TRACe:CLEar This command clears all readings and statistics from the specified
buffer. See
Clearing buffers (on page 6-24) for more information. Also
see :TRACe:CLEar (on page 12-119).
:TRACe:DELete This command deletes a buffer. See :TRACe:DELete (on page
12-124) for more information.
:TRACe:FILL:MODE This command determines if a reading buffer is filled continuously or
is filled once and stops. See
:TRACe:FILL:MODE (on page 12-125)
for more information.
:TRACe:LOG:STATe This command indicates whether the reading buffer should log
informational events. See
:TRACe:LOG:STATe (on page 12-126) for
more information.
:TRACe:MAKE
This command creates a user-defined reading buffer. You cannot use
this command on the default buffers. See
Creating buffers (on page
6-5) for more information. Also see :TRACe:MAKE (on page 12-127).
:TRACe:POINts This command reads the number of readings a buffer can store. This
allows you to change the number of readings the buffer can store.
See
:TRACe:POINts (on page 12-129) for more information.
:TRACe:SAVE This command saves data from the specified reading buffer to a USB
flash drive. See
:TRACe:SAVE (on page 12-130) for more
information.
:TRACE:SAVE:APPend This command appends data from the reading buffer to a file on the
USB flash drive. See
:TRACE:SAVE:APPend (on page 12-132) for
more information.
:TRACe:STATistics:CLEar This command clears the statistical information associated with the
specified buffer. This command does not clear the readings.
:TRACe:WRITe:FORMat
For use with writable buffers only; this function sets the units and
number of digits that are written into the reading buffer. See
:TRACe:WRITe:FORMat (on page 12-138) for more information.
:TRACe:WRITe:READing For use with writable buffers only; this function writes the data you
specify into a reading buffer. See
:TRACe:WRITe:READing (on page
12-140) for more information.
