Arbitrary Waveforms

Having done all this work it would be wise to save the settings for future use. You can do this simply by pressing the STORE key, followed by a number in the range 1 to 9 and the ENTER key. Store 0 is reserved for the factory default settings. You can recall the set-up at any time using the RECALL key.

Arbitrary waveforms are best defined on a PC and downloaded to the instrument via the RS232 or GPIB interface. Each is identified by a name with up to 16 characters.

Several commonly-used waveforms are available from the internal read-only memory (ROM) and can be recalled by pressing the EDIT then the ARB keys.

The display will look something like this:

RECALL ARB No: 14

SINX/X

ENTER TO EXECUTE

Or possibly like this:

RECALL ARB No: 03

ARB 03 IS EMPTY

ENTER TO EXECUTE

The ROM is used for the factory-preset waveforms 06 to 21 inclusive, and the internal non-volatile RAM is used for

23
