Serial Interface; Gpib Interface (Iec/Ieee Bus Interface) - R&S SMB100A Operating Manual

®
R&S SMB100A
●
<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,
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
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
ter 6.1.6.2, "GPIB Instrument
Characteristics
The GPIB interface is described by the following characteristics:
