5-68 SCPI Command Reference
:TRACe subsystem
The commands in this subsystem are used to configure and control data stor-
age into the buffer. The commands are summarized in Table 5-9.
:TRACe|:DATA
The bar (|) indicates that :TRACe or :DATA can be used as the root command
for this subsystem. From this point on, the documentation in this manual
uses :TRACe. If you prefer to use :DATA, simply replace all the :TRACe
command words with :DATA.
:CLEar command
:CLEar
:TRACe:CLEar Clear buffer
Description
This action command is used to clear the buffer of readings. If you do not
clear the buffer, a subsequent store will overwrite the old readings. If the sub-
sequent store is aborted before the buffer becomes full, you could end up
with some “old” readings still in the buffer.
:FREE? command
:FREE?
:TRACe:FREE? Read status of memory

by commas are sent to the computer. The first value indicates how many
bytes of memory are available, and the second value indicates how many
bytes are reserved to store readings.
