Connecting a Controller to the Base Unit
Settings in Base Unit
Before a link can be established between the controller and the R&S NRP, the R&S NRP must be
assigned an IEC/IEEE-bus address. In the manual control mode, this is done in the System
Æ
Remote
menu.
IEC/IEEE bus configuration:
¾
Select GPIB as the active interface.
¾
Set the GPIB address to the desired value. Any value between 0 and 30 is permissible.
Hardware Requirements
IEC/IEEE Bus
In order to control the R&S NRP via the IEC/IEEE bus, a controller with an IEC/IEEE-bus interface and
an IEC/IEEE-bus cable are required.
Switchover to Remote Control (REMOTE)
A link has been established between the controller and the R&S NRP and is assumed to have been
correctly configured.
After power up, the R&S NRP is always in the manual control mode (LOCAL). The R&S NRP is
switched to remote control irrespective of the selected interface as soon as an SCPI command is sent
to the R&S NRP. All settings are maintained when the device is switched to the REMOTE mode.
Return to Manual Operation (LOCAL)
In the remote mode, all front-panel controls are disabled. except for the
(ESC/LOCAL)
key and the
topmost toggle softkey used to insert the window with the SCPI error queue. The device remains in this
state until it is switched back to manual control either on the front panel
(ESC/LOCAL)
) or with the
remote control command
GTL.
Note:
The remote control command
LLO
also allows the
(ESC/LOCAL)
key to be
disabled. In this case, return to manual operation is only possible by remote
control or by switching the R&S NRP off and on again (Power On Reset)
.
