Section 6: Instrument programming Models 707B and 708B Switching System Reference Manual Advanced scripting for TSP The following topics describe advanced information that can help you understand how the Test Script Processor (TSP ) scripting engine works. Global variables and the script.user.scripts table When working with script commands, it is helpful to understand how scripts are handled in the instrument.
Page 189: Create A Script Using The Script.new() Command
Models 707B and 708B Switching System Reference Manual Section 6: Instrument programming Figure 69: Global variables and scripts in the runtime environment Create a script using the script.new() command Use the script.new() function to copy an existing script from the local node to a remote node.
Page 190 Section 6: Instrument programming Models 707B and 708B Switching System Reference Manual For example, to set up a two-second beep, you can send the command: beepTwoSec = script.new("beeper.enable = 1 beeper.beep(2, 2400)", "beepTwoSec") To run the new script, send the command: beepTwoSec() When you add beepTwoSec, the global variable and script.user.scripts table entries are made to the runtime environment, as shown in the following figure.
Page 191 Models 707B and 708B Switching System Reference Manual Section 6: Instrument programming To run the script, send the command: hello() Figure 71: Create an unnamed script A script becomes unnamed if you create a new script with the same name. In this circumstance, the name of the script in the script.user.scripts table is set to an empty string before it is replaced by the new script.
Page 192: Rename A Script
Section 6: Instrument programming Models 707B and 708B Switching System Reference Manual Figure 72: Create a new script with the name of an existing script Rename a script You can rename a script to a new name or be the autoexec script. To change the name of a script, use the command: scriptVar.name = "renamedScript"...
Page 193 Models 707B and 708B Switching System Reference Manual Section 6: Instrument programming If the new name is the same as a name that is already used for a script, the name of the existing script is removed and that script becomes unnamed. This removes the existing script if there are no other variables that reference the previous script.
