User Manual 301/302

Example 1

The following example programs the Model 301/302 to turn on the

main outputs and program the waveform frequency to 20 MHz. Then,

program channel A to output square waveform with an amplitude of 2

V and offset of 0.5V, and program channel B to output triangular

waveform with an amplitude of 1 V and offset of 0.5 V.

/* Reset the Model 301/302 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 20 MHz. Note that frequency setting is

common for both channels. */

:FREQuency 20e6;

/* Change channel A amplitude to 2 V and the offset to 0.5 V. */

:VOLTage 2;

:VOLTage: OFFSet 0.5;

Note that output peak voltage may never exceed ±2.5 V. Amplitude

and offset may be set freely within a 5 V window, as long as the

following limits are kept:

| offset | + (Vp-p ÷ 2) ≤ 5

/* Turn on the channel A main output. */

:OUTPut ON;

/* The following command changes control to channel B. */

:INSTrument:SELect 2;

/* Change channel 2 amplitude to 2 V and the offset to 0.5 V. */

:VOLTage 2;

:VOLTage: OFFSet 0.5;
