NI Spy Utility
This chapter introduces you to NI Spy, a utility that monitors and records
multiple National Instruments APIs (for example, NI-488.2 and NI-VISA).
Overview
NI Spy monitors, records, and displays the NI-488.2 calls made from
NI-488.2 applications. You can use it to troubleshoot errors in your
