12.8.5 Setting Up a Remote Control Connection over USB
For remote control via the USB connection, the PC and the instrument must be con-
nected via the USB type B 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 enter an address string or install a
separate driver.
Starting a remote control session over USB
1. Connect instrument and controller using USB cable. Switch them on.
2. Execute the following commands on the controller:
a) Open the port to the instrument.
viOpen (..., "USB::0x0AAD::0x01DD::100001::INSTR", ...)
b) Reset the instrument.
viRST (generator%, "*RST;*CLS")
c) Set 2 GHz frequency
viPrintf (..., "SOUR:FREQ 2GHz\n")
