Ivi-Com Programming - Keysight M8190A User Manual

8.2 IVI-COM Programming

M8190A User's Guide
IVI-COM wraps the SCPI commands into API based programming model. To select
what Module is programmed, the PXI resource string of the module is used. The IVI-
driver will automatically locate an already running Firmware that is handling the
module. If no such firmware exists, it is started automatically. This way it is
completely hidden that the IVI driver actually needs the Firmware for programming
the M8190A module.
VISA or VISA-COM are libraries from an installed I/O library such as the Keysight I/O
library to program the Firmware "instrument" using SCPI command strings. Firmware
must be already running to connect to it.
Soft Front Panel is providing the user interface. It is used for interactively changing
settings. In addition, it can log what IVI calls need to be done when changing a
setting. This can be activated with Tools  Monitor Driver calls.... In addition, you
can verify changes done from a remote program with View
The recommended way to program the M8190A module is to use the IVI drivers. See
documentation of the IVI drivers how to program using IVI drivers. The connection
between the IVI-COM driver and the Ag8190Firmware is hidden. To address a
module therefore the PXI resource string of the module, such as "PXI36::0::0::INSTR"
is used. The IVI driver will connect to an already running Ag8190Firmware. If
Ag8190Firmware is not running, it will automatically start it.
