arbitrary waveforms, pattern output provides five built-in patterns and
up to four user-defined patterns that are stored in non-volatile memory.
The built-in patterns are exponential-rise, exponential-fall,
negative-ramp, sinc, and cardiac. The default pattern output is an
exponential-rise wave.
User-defined patterns
Model 645 supports user-defined patterns. You may use the Wavepatt
waveform and pattern editor to create the patterns you want or import
the waveforms from the oscilloscope that you captured previously. For
more information on the user-defined patterns, please refer to the
on-line help of Wavepatt.
How to set up pattern output
1. Press the Utility button to enter the utility menu.
2. Press the softkey under [PATT MODE] to enter the PATTERN
menu.
3. Press the softkey under Fclk/Perd to toggle between Fclk
(frequency) and Perd (period). Refer to Section 3.4 for specifying
the frequency/period value.
4. Press the softkey under Start Addr (End Addr) for setting the start
(end) point of the pattern to output. Use the knob with the cursor
keys to change the value. Or use the numeric keypad to enter a
new value and then press the softkey under Enter to finish the

a. Press the softkey under Built In and choose the desired pattern
from the five built-ins by pressing the corresponding softkey.
b. Press the softkey under Store Wform and choose the desired
user-defined pattern by pressing the corresponding softkey.
c. One may delete a user-defined pattern by pressing the softkey
under Delete Store and choose the pattern to delete by
pressing the corresponding softkey.
