To output a stored arbitrary waveform
There are five built-in arbitrary waveforms stored in non-volatile
memory for your use. You can output these waveforms directly from
non-volatile memory.
The following steps show you how to output an
“exponential rise” waveform from memory.
1 Display the list of arbitrary waveforms.
The list contains the five built-in arbitrary waveforms (sinc, negative
ramp, exponential rise, exponential fall, and cardiac). The list may also
contain up to four user-defined arbitrary waveform names. The first
choice on this level is “
SINC
”.

This message appears on the display for approximately 10 seconds.
Repeat this step as needed.
2 Move across to the
EXP_RISE
choice.

3 Select and output the displayed arbitrary waveform.
Notice that the
Arb
annunciator turns on, indicating that the output is
an arbitrary waveform. The waveform is output using the present
settings for frequency, amplitude, and offset unless you change them.
The selected waveform is now assigned to the
Arb
key. Whenever
you press this key, the selected arbitrary waveform is output.

You can also use the knob to scroll left or right through the choices in the list.
