purpose. The port is configured for communication on a command-to-command basis
and for remote control from a program running on a connected PC.
12.1.3 USB interface
For remote control via USB connection, the PC and the instrument must be connected
via the USB interface. A USB connection requires the VISA library to be installed. VISA
detects and configures the R&S instrument automatically when the USB connection is
established. You do not have to install a separate driver.
USB resource string
The syntax of the used USB resource string is:
USB::<vendor ID>::<product ID>::<serial number>[::INSTR], where:
●
USB denotes the used interface
●
<vendor ID> is the manufacturer ID for Rohde&Schwarz
●
<product ID> is the product identification of the R&S instrument
●
<serial number> is the individual serial number on the rear of the instrument
●
[::INSTR] indicates the instrument resource class (optional)
You can retrieve the USB resource string from the "SGMA-GUI > Instrument Name >
Setup > Remote" dialog.
Example:
USB::0x0AAD::0x0088::100021::INSTR
0x0AAD is the vendor ID for Rohde & Schwarz.
0x0088 is the product ID for the R&S SGS.
100021 is the serial number of the particular instrument.
12.1.4 PCI Express interface
A PCI Express (PCIe) connector is provided on the rear panel of the instrument.
Refer to Chapter 12.3, "Advanced remote control using PCIe", on page 186 for a
description of how to set up a remote control connection via PCIe and the permitted
cables.
Via PCI Express some commands can be sent to the instrument with optimized speed
(memory-mapped remote control), e.g. frequency or level settings. Speed optimization
allows minimum setup time.
PCIe resource string
The syntax of the used PCIe resource string is:
PCIe::<vendor ID>::<product ID>::<serial number>[::INSTR], where:
●
PCIe denotes the used interface
●
<vendor ID> is the manufacturer ID for Rohde & Schwarz
