OM4006ATEClientNET
assembly
This assembly includes a basic interface for retrieving MATLAB variable values
and an object oriented interface that includes specialized .NET classes for all
of the OM4000 instrument speci
fi c variables. This interface allows a client
application to read and set all analysis parameters such as Block Size and Record
Length. It also has the ability to connect or disconnect to/from a scope based on
IP address as well as trigger single acquisitions. Additionally, the application can
register for events that occur at the end of blocks and records.
To get started add the following (highlighted in yellow) reference to your ATE
Client application. The
fi le can be found in the folder where OM4000 OUI is
installed.
Once the reference is added it can be browsed to understand the available
functionality. Double click on the reference to bring up the Object browser.
Scroll down from Optametra.OM4006.OM4006ATEClient and double-click on
OM4006ATEClient:
The right pane on the object browser should look like the following image:
Basic method for getting
MATLAB variable values
The following is an example code block that references the OM4006 Client,
allocates a new object, registers the BER variable for the block update, connects
to a scope, acquires a single block and saves it to a local variable. This method
is straight forward but requires more code to extract values to local variables. It
allows for simpler implementation of code to extract customer de
fi ned variables.
It requires that case sensitive strings be passed to the Register and Get methods as
shown in the following code.
