Script examples
Script using commands and statements only
The script in Table 12-1 sweeps voltage (1V to 5V) and measures current at each step. The five
current readings are returned to the host computer:
NOTE When creating a script using the Test Script Builder, only the chunk is
typed in as shown above. See
Using Test Script Builder in Section 13
for details on creating, loading and running the script.
When creating a script using a programming language, shell
commands must be included to manage interactions between the
host computer and TSP. The
loadscript command loads the script
into the Series 2600A and endscript signifies the end of the script.
Script using a function
TSL facilitates grouping commands and statements using the function keyword. Therefore, a
script can also consist of one or more functions. Once a script has been RUN, the host computer
can then call a function in the script directly.
The script in Table 12-2 contains an ICL command to set measurement speed (NPLC) and a
function (named sourcev). When this script is run, the measurement speed will set to 0.5 PLC and
make the
sourcev function available for calling.
When calling the function, you must specify the source voltage in the argument for the function.
For example, to set the source to 2V, call the function as follows:
sourcev(2)
