VISA名稱(儀器描述)的字串有以下的格式
Interface Type[Board Index]::Address::VISA Class
以下是一些VISA名稱的例子
‧GPIB0::INTFC
‧GPIB0::3::INSTR
‧ASRL1::INSTR
‧TCPIP::www.yahoo.com::INSTR
根據下面KnowledgeBase 2CMST8V的連結:如何使用NI-VISA控制乙太網路端的儀器?,有更多TCP/IP來源的更多資訊。板子號碼只有被用在系統中有超過一個介面種類時出現。例如一個系統有插入兩個GPIB板,一個被指為GPIB0而另一個被指為GPIB1,在這種例子中,板子號碼必須在來源名稱被用到。且若註名為"GPIB0::3::INSTR"及"GPIB::3::INSTR"會被視做同一個來源,因為在介面種類後的0是可選擇性的。對於VXI儀器,"位址"參數是儀器的邏輯位址。對於GPIB儀器,是GPIB的主要地址。對於串列儀器,位址並沒有被使用。舉例來說"ASRL1::INSTR"在個人電腦被當作COM 1的序列埠的敘述。
