User Manual 1173.9463.02 ─ 02
For VXI-11 the "Assigned Instrument" number is also part of the VISA resource string,
with instrument 1 mapped to "inst0" and instrument 2 mapped to "inst1".
SCPI command:
n/a
Data Port (TCPIP only)
The data port number is part of the TCPIP VISA resource string. Different data ports have
to be used for different channels (to address different sub-instruments). The data port is
used for all protocol modes.
Consider the following rules:
●
In order to modify the port number it is recommended to enter a 0. A free port in the
range 1024 to 32767 is then assigned automatically.
●
Alternatively you may enter a port number in that range manually.
●
Never configure a port number between 1 and 1023. These "well-known ports" are
reserved for specific services.
SCPI command:
Control Port (TCPIP only)
The control port is only relevant for protocol mode "Agilent". It can be used to set up an
optional control connection for transfer of emulation codes. The control port number is
displayed for information. It cannot be modified.
SCPI command:
n/a
Protocol Mode (TCPIP only)
The protocol mode defines the support of control messages, e.g. polling or service
request:
●
RAW
: no support for polling and service request (but best performance)
●
Agilent
: emulation codes via control connection (control port)
●
IEEE1174
: emulation codes via data connection (data port)
SCPI command:
Board Name (IEC only)
One or two optional GPIB bus interfaces can be installed (options R&S CMW-B612A and
R&S CMW-B612B). The two interfaces have different board names. Board number 0 is
related to connector "IEEE 488 CH 1", board number 1 to connector "IEEE 488 CH 2".
SCPI command:
n/a
Primary Address (IEC only)
The primary address is part of the GPIB VISA resource string. Different primary
addresses have to be used for different channels (to address different sub-instruments).
SCPI command:
