R&S SGT100A
The instrument also supports the fast socket channel. For details, see
"Advanced Remote Control Using Fast

10.1.3 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::0x00EC::100021::INSTR
0x0AAD is the vendor ID for Rohde&Schwarz
0x00EC is the product ID for the R&S SGT
100021 is the serial number of the particular instrument

10.1.4 PCI Express Interface

A PCI Express (PCIe) connector is provided on the rear panel of the instrument.
Refer to
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. This allows mini-
mum 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
