●
<vendor ID> is the vendor ID for Rohde&Schwarz
●
<product ID> is the product ID for the R&S instrument
●
<serial number> is the individual serial number on the rear of the instrument
Example:
USB::0x0AAD::0x0054::100001::INSTR
0x0AAD is the vendor ID for Rohde&Schwarz
0x0054 is the product ID for the R&S
SMB
100001 is the serial number of the particular instrument
6.1.5 Serial Interface
Remote control via the serial interface is possible either via RS232 interface or via a
Bluetooth connection. The controller/Bluetooth device and the instrument must be con-
nected via an external USB/serial-adapter (see recommended extras, data sheet) and
a serial crossover (null modem) cable. A USB connection requires the VISA library to
be installed on the controller. VISA detects and configures the R&S
SMB automatically
when the USB connection is established.
Serial address
The used serial address string is:
ASRL[0-9][::INSTR]
Where
ASRL[0-9]
determines the number of the COM port on the controller side, that
has to be used for the serial connection.
Access via a bluetooth device requires the entry of the bluetooth pin in addition (see
Chapter 5.2.3.18, "Security" , on page 114).
To enable an error-free and correct data transmission, the parameters of the generator
and the controller must have the same setting. The serial interface is preset for a baud
rate 115200, no parity and one stop bit. The parameters can be manually changed in
"Remote Channel Settings" dialog (see
Chapter 5.2.3.14, "Remote Channel Settings" ,
on page 108).
6.1.6 GPIB Interface (IEC/IEEE Bus Interface)
To be able to control the instrument via the GPIB bus, the instrument and the controller
must be linked by a GPIB bus cable. A GPIB bus card, the card drivers and the pro-
gram libraries for the programming language used must be provided in the controller.
The controller must address the instrument with the GPIB bus address (see
Chap-
ter 6.1.6.2, "GPIB Instrument Address" , on page 243).
Characteristics
The GPIB interface is described by the following characteristics:
●
Up to 15 instruments can be connected
