USB
If the R&S NRP is connected to a controller via a USB 1.1 interface, it logs on as a USBTMC (USB test
and measurement class) device, provided that USB is selected as a remote interface in the
SystemÆRemote menu. The USBTMC standard describes how IEEE 488.2-compatible communication
with can be implemented via USB.
As with remote control via VXI11, the use of a VISA distribution that must include a USBTMC driver is
recommended for remote control via USB. The VISA resource identifier used to identify a USBTMC
device has the following format:
USB::<vendor ID>::<product ID>::<serial number>::INSTR
<vendor ID>
0x0aad
<product ID>
0x001b
<serial number>
The serial number is a string that can be found in the SystemÆSystem Info menu.
In addition, the VISA resource identifier appears on the R&S NRP display if the USB remote interface is
selected.
