6.1.3.1
Setting the Device Address
The GPIB address (primary address) of the instrument is factory-set to 20. It can be
changed manually in the "SYSTEM > SETUP > Remote Settings" tab or via remote
control. For remote control, addresses 0 through 30 are permissible. The GPIB
address is maintained after a reset of the instrument settings.
SCPI commands:
SYSTem:COMMunicate:GPIB[:SELF]:ADDRess
6.1.3.2
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 this is
not the case, 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 10.2.3.2, "Interface Mes-
on page 1256). This 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.
6.1.4 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. On the other hand, it is often prefera-
ble to control a previously configured measurement manually in order to observe the
result on the screen.
The analyzer provides a number of 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" softtol. 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.
