VINStrument
The
VINStrument
subsystem operates with the
[SOURce:]ARBitrary
and
[SOURce:]PM subsystems to control the virtual instrument features of the
Agilent E1445A. These features include the ability to use the VXIbus Local Bus
and normal data transfer bus to download data to the segment and segment sequence
memories, directly drive the main output DAC, and provide phase deviations for
sine waves.

Comments
•
The available modes are:
–
CONSume: Local Bus data is used and not passed through. This mode must be
selected when downloading segment and segment sequence memory data, directly
driving the main output DAC, and providing phase deviations for sine waves.
–
OFF: The Local Bus interface is disabled. Local Bus data is neither used nor
passed through.
–
PIPeline: Local Bus data is passed through and not used. Select this mode when
data should be transparently passed through the Agilent E1445A.
