R&S FSQ Remote Control – Basics
5.4.3.2 Return to Manual Operation
Starting Remote Control
Return to manual operation is possible via the front panel or via RS-232 interface.
Manually:
Press the LOCAL softkey or the PRESET key.
• Before the transition, command processing must be completed as otherwise
transition to remote control is performed immediately
• The keys can be enabled again by sending the control string "@LOC" via RS-
232 (see chapter “Maintenance and Instrument Interfaces”, section “RS-232-C
Interface (COM)” on page 8.7).
Via RS-232:
v24puts(port,"@LOC");
Set instrument to manual operation.
5.4.3.3 Restrictions
The following restrictions apply if the unit is remote-controlled via the RS-232-C
interface:
No interface messages, only control strings (see interface description in chapter
“Maintenance and Instrument Interfaces”, section “RS-232-C Interface (COM)” on
page 8.7).
Only the Common Commands *OPC? can be used for command synchronization,
*WAI and *OPC are not available.
Block data cannot be transmitted.
5.4.4 Remote Control in a Network (LAN Interface)
Via the LAN interface, the R&S FSQ can be remotely controlled in a local area network.
The LAN interface consists of a connector, a network interface card and protocols
(VXI-11 and RSIB). For details on the connector and its use refer to the Quick Start
Guide, chapter 1, "Front and Rear Panel".
Instrument access via VXI11 or RSIB is usually achieved from high level programming
platforms by using VISA as an intermediate abstraction layer. VISA encapsulates
the low level VXI, RSIB or even GPIB function calls and thus makes the
transport interface transparent for the user. The necessary VISA library is available
as a separate product. For details contact your local R&S sales representative.
