Example program code
The example code to configure the Model 707B or 708B and System SourceMeter Instrument shown
below is identical to the code used in Example 1. However, in this example, all commands are sent to
the Model 707B or 708B. This example can be run using TSB Embedded. Commands for the Model
2635 System SourceMeter have the TSP-Link node number appended to the beginning of the
command (
node[2]
).
In the following table, the Model 707B or 708B sends the commands in the shaded rows to the
System SourceMeter instrument through the TSP-Link interface. Commands in unshaded rows are
executed by the Model 707B or 708B.
