4349B
T o Control the 4349B from an External Computer
Most measurements can be modeled the following simple three step sequence:
1. Set up the 4349B .
Typically , you begin the setup step by sending the reset command to set the instrument to
its default settings . Next, if you need values dierent from the default settings , change the
settings one by one as required.
2. Trigger the measurement.
The trigger may be generated automatically by steps taken in your setup commands , or you
can send an explicit trigger command.
3. Retrieve the measurement data
The following sections describes how to perform the tasks at each step .
Figure 4-1 shows a simple resistance measurement program.
