What To Do Now
When writing low level code to operate the Model 3151/3151A, follow
the instructions in this chapter to understand the meaning and
response that each command generates. Examples contained in the
following paragraphs show basic techniques on how to program
output waveforms.
Example 1
The following example programs the Model 3151/3151A to turn on
the main output, generate a square waveform, program the
frequency to 2 MHz, program the amplitude to 5 V and offset to 2.5
V.
/* Reset the Model 3151/3151A to its default condition as listed in
Table 3-1.*/
:RESet;
/* Change the output waveform to square. Note that there is no need
to use the FUNC:MODE command as the default value after RESet
is FIXed.*/
:FUNCtion:SHAPe SQUare;
/* Change the frequency to 2 MHz.*/
:FREQuency 2e6;
/*Change the amplitude to 5 V and the offset to 2.5 V.*/
:VOLTage 5;
:VOLTage: OFFSet 2.5;
