Remote buffer operation
You can control the Model 2461 buffers through a remote interface using SCPI or TSP remote
commands.
This section provides a summary of some of the remote commands available to control and access
data stored in buffers; however, this section does not describe all of the available commands. See the
following sections for command descriptions:
• For information about SCPI commands, see the SCPI command reference (on page 6-1)
• For information about TSP commands, see the TSP command reference (on page 8-1)
Storing data in buffers
Using SCPI commands:
The table below lists the SCPI commands that you use for data storage.
Command Description
This command creates a user-
defined reading buffer. You cannot use
this command on the default buffers. See Creating buffers (on page
3-5). Also see :TRACe:MAKE (on page 6-165).
This command saves data from the specified reading buffer to a USB
flash drive. See :TRACe:SAVE (on page 6-168).
This command appends data from the reading buffer to a file on the
USB flash drive. See :TRACE:SAVE:APPend (on page 6-170).
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 6-167).
For use with writable buffers only; this function sets the units and
number of digits that are written into the reading buffer.
:TRACe:WRITe:FORMat (on page 6-178).
For use with writable buffers only; this function writes the data you
specify into a reading buffer. See :TRACe:WRITe:READing (on page
This command clears all readings and statistics from the specified
buffer. See Clearing buffers (on page 3-21). Also see :TRACe:CLEar
This command clears the statistical information associated with the
specified buffer. This command does not clear the readings.
This command determines if a reading buffer is filled continuously or
is filled once and stops. See :TRACe:FILL:MODE (on page 6-163).
This command indicates whether the reading buffer should log
informational events. See :TRACe:LOG:STATe (on page 6-164).
This command contains the number of readings in the specified
buffer. See :TRACe:ACTual? (on page 6-156).
This command returns the last index in a reading buffer. See
:TRACe:ACTual:END? (on page 6-157).
This command returns the starting index in a reading buffer. See
:TRACe:ACTual:STARt? (on page 6-158).
This command deletes a buffer. See :TRACe:DELete (on page 6-
163).
