10 Remote Control
By default, the R&S®HMC804x includes an Ethernet and a
USB interface.
In addition to a LAN interface, the R&S®HMC804x includes
a USB device port. For this interface, the user can select
if the instrument is accessed via virtual COM port (VCP)
or via USB TMC class. The R&S®HMC804x is optionally
available ex factory with an integrated GPIB interface
(R&S®HMC804x-G). The GPIB interface has its own inter-
face slot on the rear panel.
10.1 USB VCP
The traditional version of the VCP (virtual COM port) al-
lows the user to communicate with the R&S®HMC us-
ing any terminal program via SCPI commands once the
corresponding Windows drivers have been installed.
The actual USB-VCP driver can be downloaded from the
ROHDE & SCHWARZ homepage for free. If a connection
between PC and the instrument has been established and
no R&S®HMC USB-VCP driver is installed, the operating
system answers with “Found New Hardware”. In addition,
the “Found New Hardware Wizard” is displayed. Only in
this case the USB-VCP driver must be installed. Further
To enable communication, the selected interface and the respec-
tive settings in the instrument must be identical to the selections
for the PC.
Fig. 10.1: Rear panel
All currently available USB VCP drivers have been fully tested
and released for Windows XP™, VISTA™, Windows 7™, Win-
dows 8™ and Windows 10™ (32 + 64 Bit).
