Or, the address string can be replaced by a symbolic name such as:
Dim resourceName as String
resourceName = "VXI0::210::INSTR"
Closing an Instrument Session
Sessions (instrumentHandle) opened with the HPE6432_init function
are closed with the function:
HPE6432_close (ViSession instrumentHandle);
When no further communication with an instrument is required, the
session must be explicitly closed (HPE6432_close). Agilent Technologies
VISA does not remove sessions unless they are explicitly closed. Closing
the instrument session frees all data structures and system resources
allocated to that session.

Agilent Technologies VISA Data Types
The driver functions use Agilent Technologies VISA data types. Agilent
Technologies VISA data types are identified by the ‘Vi’ prefix in the
data type name (for example, ViInt16, ViUInt16, ViChar). The
visatype.h file contains definitions of the Agilent Technologies VISA
data types.

Querying the Instrument
The Agilent Technologies E6432A VXIplug&play driver has several
functions that can be used to query the instrument. Variables to contain
the data returned by the query must be of sufficient size and be
declared before the function is called.
