The USB interface must be chosen in the function generator and
does not need any setting. At the first connection Windows™
asks for a driver. The driver you can find on the delivered CD or
on our homepage www.hameg.com at the download area for the
HO720/HO730. The connection can be done via the normal USB
or via the virtual COM port (VCP). The description how to install
the driver you can find in the HO720/730 manual.
If the virtual COM port will be used, you must set
USB as interface at the function generator.
9.3
Ethernet (Option HO730)
The optional interface card HO730 does have a USB and Ether-
net connection. The settings of the parameter at the function
generator are done after selecting ETHERNET as the interface
and the soft key PARAMETER is chosen. You can set anything
including a fix IP adress. Alternative you can chose a dynamic
IP setting via the DHCP function. Please ask your IT department
for the correct setting at your network. If the function generator
does have an IP adress you can open your web browser and put
this IP adress into the adress line (http//xxx.xxx.xxx.xx). Since
the HO730 does have a webserver integrated it will open a site
with informations about the HMF, the interface and it's setting.
Fig. 9.1: Web server with device data
On the left side there are links to „Screen Data" which make it
possible to transfer a screen dump to the PC (using the right
mouse click this can be transferred to the clip board for further
use). The link „ SCPI Device Control" open a site with a console
to send remote SCPI commands to the function generator.
In general, the HO730 works with a RAW-Socket
communication to control the instrument and to
request the measurement values.
Therefore, a TMC or similar protocol is not sup-
ported.
9.4
IEEE 488.2 / GPIB (Option HO740)
The optional interface card HO740 does have a IEEE488.2 con-
nection. The settings of the interface can be done in the function
generator after chose the IEEE 488 as interface and hitting the
soft key PARAMETER. Further information you can find at the
manual of the HO740 at the download area on our homepage
www.hameg.com.
