Getting Started 4338B
T o Control the 4338B from an External Computer
Most measurements can be modeled on the following simple three step sequence:
1. Set up the instrument.
Typically , you begin the setup step by sending *RST 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. 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.
The following sections describes how to perform the tasks at each step .
Figure 4-1 shows a simple capacitance measurement program.
:
! Step 1
OUTPUT 717;"*RST" R esetting
OUTPUT 717;":INIT:CONT ON" Initiating trigger system
OUTPUT 717;":CALC1:FORM REAL" Primary parameter: R
OUTPUT 717;":CALC2:FORM NONE" Secondary parameter: None
OUTPUT 717;":TRIG:SOUR BUS" Trigger source: Bus
! Step 2
OUTPUT 717;"*TRG" Triggering
! Step 3
