Getting Started 4339B
T o Control the 4339B from an External Computer
Most measurements can be modeled by the following simple four step sequence:
1. Set up the instrument.
Typically , you begin the setup step by sending the *RST 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
may send an explicit trigger command. T o select the trigger source , send the :TRIG:SOUR
command with the trigger source parameter . When you select BUS as the trigger source ,
sending *TRG triggers a measurement and retrieves the measurement data.
3. Retrieving the data.
4. Turn OFF the test voltage and end the measurement.
Figure 4-1 shows a simple resistance measurement program.
