exponential-rise, exponential-fall, negative-ramp, sinc, and cardiac. The

default arbitrary waveform is an exponential-rise wave.

For each user-defined waveform, one may create up to 262,144 (256k)

points from the remote interface. If you choose an arbitrary waveform as

the modulating waveform for AM, FM, PM, or PWM, the waveform is

automatically limited to 4k points and the extra points will be removed by

decimation.

User-defined waveforms

Model 645 supports user-definded waveforms. You may use the

Wavepatt waveform and pattern editor to create the waveforms you

want or import the waveforms from the oscilloscope that you captured

previously. For more information on the user-defined waveforms, please

refer to the on-line help of

Wavepatt.

How to output a built-in arbitrary waveform

1. Press the Arb button to choose arbitrary waveform output.

Press the softkey under Select Wform and then the softkey under

Built In.

Choose the desired waveform from the five built-ins by pressing

the corresponding softkey.

Refer to Chapter 3 for configuring frequency/period, amplitude

and dc offset voltage.

Press the Graph button to view all the waveform parameters.
