MAC Address
MAC (Media Access Control) address, also called hardware address, is used for
defining the position of the network device. For a generator, the MAC address is
always unique. It is always used to identify the instrument while assigning IP
address for instrument. MAC address (48 bits, namely 6 bytes) is usually expressed
in hexadecimal format, such as 00-14-0E-42-12-CF.
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 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::172.16.2.13::INSTR.
