Before you can use the instrument object to write or read data,
you must connect it to the instrument whose address or port is specified
in the creation function. You connect an interface object to the instrument
with the fopen
function.
fopen(g)
Some properties are read-only while the object is connected
and must be configured before using fopen
. Examples
include the InputBufferSize
and the OutputBufferSize
properties.
You can determine when a property is configurable with the propinfo
function, or by referring
to the properties documentation.
Note
You can create any number of instrument objects. However, at any time, you can connect only one instrument object to an instrument with a given address or port.
You can examine the Status
property to
verify that the instrument object is connected to the instrument.
g.Status ans = open
As illustrated below, the connection between the instrument object and the instrument is complete, and you can write and read data.
