User Manual 1179.1341.02 ─ 05
Example:
USB::0x0AAD::0x0277::100001::INSTR
0x0AAD is the vendor ID for Rohde
&
Schwarz.
0x0277 is the product ID for the R&S
SMM100A
100001 is the serial number of the particular instrument.
12.2.2.2
RS232 resource string
The RS232 resource string represents the addressing scheme for a device connected
to the serial interface of the instrument.
The USB resource string syntax is as follows:
ASRL<port number>[::INSTR]
ASRL
is the name of the serial interface
<port number>
is the number of the serial interface
Example:
ASRL1::INSTR
12.2.3
GPIB interface (IEC/IEEE bus interface)
To control the R&S
SMM100A over the GPIB bus, the instrument and the controller PC
must be connected with a GPIB bus cable. A GPIB bus card, the card drivers and the
program libraries for the used programming language must be installed on the control-
ler.
For description of the characteristics, control commands and messages of the GPIB
interface, refer to
GPIB address
The controller PC addresses the instrument with the GPIB bus channel, see
ter 12.5.3, "GPIB address settings"
on page 603. GPIB provides channel addresses
from 0 to 30.
The GPIB resource string syntax is as follows:
GPIB:://<channel>[::INSTR]
GPIB
= denotes the used interface
<channel address> = the used channel
[::INSTR]
= indicates the instrument resource class (optional)
Note:
If the VISA implementation supports the GPIB interface, you can optionally
define the VISA Instrument Control Resource (INSTR). It is used to define the basic
operations and attributes for a device, such as reading, writing, or triggering.
