11.1.3
Returning to Manual Operation
Before you switch back to manual operation, all remote command processing must be
completed. Otherwise, the instrument will switch back to remote control immediately.
► Press the "Local" softkey or the [PRESET] key, or use the following GPIB com-
mand:
status = viGpibControlREN(vi, VI_GPIB_REN_ADDRESS_GTL)
If you select the "Local" softkey while a self-alignment or a self-test is still running
(which was started remotely), the instrument only returns to the manual operation state
when the alignment or test is completed.
11.1.4
SCPI Command Structure
SCPI commands consist of a header and, in most cases, one or more parameters. The
header and the parameters are separated by a "white space" (ASCII code 0 to 9, 11 to
32 decimal, e.g. blank). The headers may consist of several mnemonics (keywords).
Queries are formed by appending a question mark directly to the header.
The commands can be either device-specific or device-independent (common com-
mands). Common and device-specific commands differ in their syntax.
11.1.4.1
Syntax for Common Commands
Common (= device-independent) commands consist of a header preceded by an aster-
isk (*), and possibly one or more parameters.
