Chapter 5 NI Spy Utility

Exiting NI Spy
When you exit NI Spy, its current configuration is saved and used to
configure NI Spy when you start it again. Unless you save the data captured
in NI Spy before you exit, that information is lost.
To save the captured data, click on the red circled X button on the toolbar
and select File»Save As to save the data in a
.spy
file. After you save your
data, select File»Exit to exit the NI Spy utility.
Performance Considerations
NI Spy can slow down the performance of your NI-488.2 application, and
certain configurations of NI Spy have a larger impact on performance than
others. For example, configuring NI Spy to record calls to an output file or
to use full buffers might have a significant impact on the performance of
both your application and your system. For this reason, use NI Spy only
while you are debugging your application or in situations where
performance is not critical.
