VISA Descriptor
VISA (Virtual Instrument Software Architecture) is an advanced application
programming interface developed by NI (National Instrument) for communications
with various instrument buses. It uses the same method to communicate with
instruments regardless of the types of the instrument interfaces (GPIB, USB,
LAN/Ehternet or RS232). The GPIB, USB, LAN/Ethernet or RS232 instrument which
wants to communicate with VISA is called "resource".
VISA descriptor is the resource name and describes the accurate name and
location of the VISA resource. If LAN interface is currently used for communication
with the instrument, the VISA descriptor is TCPIP0::172.16.3.33::INSTR.
IP Configuration Mode
IP configuration mode could be DHCP, AutoIP or ManualIP. If the network is
disconnected currently, there will be nothing to be displayed behind "IP
Configure:". In different IP configuration modes, the configuration ways of network
parameters (such as IP address) are different.
1. DHCP
In DHCP mode, DHCP server in the current network assigns LAN
⚫
parameters, e.g. IP address, for the generator.
pulse DHCP to select "On" or "Off" to turn DHCP mode on or off. The
⚫
default is "On".
2. AutoIP
In AutoIP mode, the generator acquires IP address within 169.254.0.1 and
⚫
169.254.255.254 and subnet mask 255.255.0.0 automatically according to
the current network configuration.
pulse AutoIP to select "On" or "Off" to turn AutoIP mode on or off. The
⚫
default is "On". When DHCP and AutoIP modes are turned on at the same
time, the instrument will first use DHCP mode. Therefore, to enable this
mode, set DHCP as "Off".
3. ManualIP
In ManualIP mode, the LAN parameters of the generator, e.g. IP address,
⚫
are defined by users.
