trol. For remote control, addresses 0 through 30 are permissible. The GPIB address is
maintained after a reset of the instrument settings.
SCPI commands:

Returning to manual operation
Return to manual operation can be initiated via the front panel or via remote control.
●
Manually: tap the Local softkey in the remote screen.
●
Via GPIB bus: CALL IBLOC(device%)
●
Via RSIB or VXI-11 protocol: @LOC and @REM can be used to switch from
remote to manual control and back.
Local lockout
Before returning to manual control, command processing must be completed. If not,
the analyzer switches back to remote control immediately.
Returning to manual control by tapping the "Go to Local" softkey can be disabled, e.g.,
by the Local Lockout Message (via GPIB: LLO; see
Chapter 12.3.3.2, "Interface mes-
on page 1542). The lockout prevents unintentional switch-over, i.e. return to
manual control is possible via remote control only.
Returning to manual control via the front panel keys can be enabled again, e.g. by
deactivating the REN control line of the GPIB bus.
6.1.5
Combining manual and remote control
Using a remote control script is the quickest and easiest way of performing complica-
ted tasks which need to be repeated many times. However, it is often preferable to
control a previously configured measurement manually to observe the result on the
screen.
The analyzer provides various tools for combining manual and remote control:
●
User Keys
The remote control commands
SYSTem:USER:KEY...
place up to 8 softkeys with
arbitrary functionality on the remote screen. The softkeys appear in the "User
Menu" tab of the "Remote" softtool. When a softkey is selected, the ESR bit no. 6
(User Request) is set, and the response for
SYSTem:USER:KEY?
is changed. This
behavior can serve as a control mechanism in remote control scripts.
