DESCRIPTION
The Set Query Terminator (
resp
: This argument specifies the response terminator for general purpose queries issued by the controller.
These queries are queries that do not request High/Low/Last or Acquisition Buffer data. This terminator is used
in all query responses unless the query refers to data in the High/Low/Last registers or the Acquisition Buffer. In
these cases, these types of queries have separate terminators as described below.
hll
: This argument specifies the channel terminator to be used for queries which request data residing in the
High/Low/Last registers. When this terminator is specified, the terminator will be inserted between each channel
response when a High/Low/Last register query request is made. The queries that request High/Low/Last register
data are
scan
: This argument specifies the terminator which will follow each scan that is output when a query request is
made for Acquisition Buffer data. When a query request is made for Acquisition Buffer data, this terminator will
be used to terminate each scan as it is output to the interface. This will be true except for the last scan in the
block. In this case, the trigger block terminator will be used to terminate the scan and the block. The only query
command which requests Acquisition Buffer data is the Read Buffered Data (
block
request is made for Acquisition Buffer data. When a query request is made for Acquisition Buffer data, this
terminator will be used to terminate each trigger block as it is output to the interface. This terminator will be in
effect during Read Buffer Data (
output will be terminated by the defined trigger block terminator rather than the scan terminator.
Each of the above four arguments may be defined with one of the following terminator types, where

sep
: This argument specifies whether or not a separator character should be placed between each returned
reading in the buffer scan data. This field will be in effect during Read Buffer Data (
this field is interpreted as follows:
Place a separator, whose value is determined by the current Set User Terminator (
