User Manual 301/302

generator is programmed to output a sine waveform, the APPL?

Command returns: "1e+6, 2, 0 , 0.

Example 2

The following example programs the Model 301/302 using the APPLy

command. This example turns on the main output, generates a square

waveform, programs frequency to 2 MHz, programs amplitude to 1 V

and offset to 1 V. It also changes the square wave duty cycle

parameter to 25%.

/* Reset the Model 301/302 to its default condition as listed in Table 3-

1. */

:RESet;

/* Change the output waveform to square, frequency to 2 MHz,

amplitude to 1 V, offset to 1 V and duty cycle to 25%. Note that there

is no need to use the FUNC:MODE command because the default

value after RESet is FIXed. */

:APPLy:SQUare 2e6,1,1,25

/* Turn the main output on. */

:OUTPut ON

/*Turn the SYNC output on, if required. */

:OUTPut:SYNC ON

If the above commands are executed correctly, a square waveform

will be seen on your oscilloscope.

Selecting the

Active Channel

On power up, the instrument defaults to channel A. That means that

each command sent to the generator affects channel A parameters. If

you want to send commands to the other channel, you must switch the

input to the other channel. Proceeding channel selection, all

commands will affect the selected channel only. Use the following

command to select the channel you want to program:

INSTrument:SELect {1 | 2}

When “1” is selected, commands will control parameters that are

unique for the channel A output. Selecting “2”, modifies the control to

channel B parameter. The default option is “1”. Parameters that are

common to both channels may be programmed from either path.
