DS_n?
Data Store Value Query
Syntax:
DS_n? <number>
where n is either A or B
Parameters:
The parameter <number> rounds to an integer and represents the data store
value that is being queried. The range of <number> is 1 to n; where n is the
number of values stored in the data store buffer (see DSCNT_n?). A parameter
of 1 represents the oldest data value in the data store, 2 the second oldest and
so on.
Function:
This query is used to query an individual data value from the data store
buffer. If the parameter is out of range then an execution error message will
be generated and nothing will be returned. It is recommended to use the
DSCNT_n? query to determine how many values have been stored in the data
buffer.
Returns:
<status>,<number>
<status> is an integer that represents the status of the returned value. <sta-
tus> will be 0 for ok, 1 for over range, 2 for detector saturated, 3 for data error
and 4 for ranging.
<number> is a floating point number in the exponential format.

DSBUF_n
Data Store Buffer Behavior Select
Syntax:
DSBUF_n <state>
where n is either A or B
Parameters:
The parameter <state> is of type <number>. If the number rounds to 0 then
data store FIXED BUFFER behavior is enabled. Otherwise, data store SLIDE
BUFFER behavior is enabled.
Function:
This command selects data store FIXED BUFFER or SLIDE BUFFER behavior.
