Programming interaction
This part of the workspace is where you interact with the scripts that you are building in Test Script
Builder (TSB). The actual contents of the programming interaction area of the workspace can vary.
You can send commands from the Instrument Console command line, retrieve data, view variables
and errors, and view and set breakpoints when using the debug feature. For additional information,
refer to the online help that is accessible from Test Script Builder (TSB).
Password management
The Model 2657A has password capabilities that let you decide how to password protect the
instrument. You can enable password policies to lock the instrument. Locking the instrument prevents
unauthorized access to any remote interface and reserves the instrument exclusively for your use.
