Control using a VISA driver
About VISA
Virtual Instrument Software Architecture (VISA), which consists of a hardware driver, configu-
ration utility, and connection manager, is one of the several typical frameworks used for test-
ing and measurement in manufacturing sites.
VISA supports various types of bus communication. VISA drivers are already used in several
measuring instrument manufacturers. Programming languages that support Windows COM
or DLL libraries can call VISA functions.
Compatibility with VXI-11
VXI-11 is a protocol for connecting measuring instruments to a PC. VISA complies with VXI-
11 specifications.
The PAV is compatible with the VXI-11 protocol.
•
VXI-11 Device_link: Starts a link with a measuring instrument.
•
VXI-11 Device_write: Writes text in a measuring instrument.
•
VXI-11 Device_read: Reads text from a measuring instrument.
•
VXI-11 Destroy_link: Disconnects the link to a measuring instrument.
Starting a VISA connection
Using a VISA library, you can easily create test programs and auto control programs.
The VISA functions that the PAV supports include Open, Read, Write, and Close.
VISA resource assignment is written for each PAV. You can view the PAV LAN descriptor
from the PAV home page. The VISA resource uses the PAV’s IP address or host name.
Communication using VISA
The VISA write function sends SCPI commands to the PAV. The VISA read function reads the
responses of SCPI queries.
Example of PAV LAN VISA resource assignment:
Format:
TCPIP[board]::IP address/Host Name[::LAN device name][::INSTR]
[board] is the LAN card number. “0” is optional.
The default value of [::LAN device name] is “inst0”.
[::INSTR] is optional.
Example: TCPIP::10.225.26.60::inst0::INSTR
TCPIP1::PAV10-40-001::INSTR
