according to their definition in the IEEE 488.2 and SCPI 1999.0 standard:
Common commands
are precisely defined in the IEEE 488.2 standard in terms of
function and notation. They relate to functions such as the
management of standardized status registers, resetting and self
test.
Device-specific commands
relate to functions that depend on device characteristics such as
the frequency setting. Most of these commands are also
standardized by the SCPI Consortium (
Æ
"
SCPI Standard
", page
5.6
). The standard allows device-specific extensions of
commands.
Parallelism:
Overlapping commands
can be executed while another command is being executed.
Sequential commands
can only be executed when the execution of all other commands
is completed.
Note
:
In the R&S NRP, only the remote control commands
INIT:IMM
and
CAL:ZERO:AUTO ONCE
can overlap with other commands.
Responses
are messages sent by the device to the controller after a query. This may be measurement results, for
instance, or device status information.
