Pattern output operation
Pattern output allows you to specify a pattern of up to 256k points in 16-bit resolution. Similar to
arbitrary waveforms, pattern output provides five built-in patterns and up to four user-defined
patterns that are stored in nonvolatile memory. The built-in patterns are exponential-rise,
exponential-fall, negative-ramp, sinc, and cardiac. The default pattern output is an
exponential-rise waveform.
You can import waveforms captured with an oscilloscope, or create a custom pattern with the
KiWAVE™ waveform and pattern editor software provided with the instrument. Refer to Section 7,
KiWAVE™ software installation for software installation instructions.
To set up pattern output:
1. Press the Utility key to access the utility menu.
2. Press the soft key under PATT / Mode to access the pattern menu.
3. Press the soft key under Fclk / Perd (Figure 5-21) to choose between frequency (Fclk) and
period (Perd). Refer to Section 4, Setup Basics for assistance.

Setting frequency or period for pattern output
4. Press the soft key under Start / Addr to specify a start point for the pattern output
(Figure 5-22). Use the navigation wheel with the cursor keys to change the value, and then
press another soft key to finish the entry and exit. Or use the numeric keypad to enter a
desired value and then press the soft key under Enter to finish the entry, or the soft key
under Cancel to cancel the changes.

5. Press the soft key under End / Addr to specify an end point for the pattern output
(Figure 5-23). Use the navigation wheel with the cursor keys to change the value, and then
press another soft key to finish the entry and exit. Or use the numeric keypad to enter a
desired value and then press the soft key under Enter to finish the entry, or the soft key
under Cancel to cancel the changes.

6. Press the soft key under Output / Setup.
a) Press the soft key under RPT. to choose between ON and OFF (Figure 5-24).
Select ON to enable the repeat output of the pattern.
b) Press the soft key under CLK to select rising edge or falling edge.
c) Press the soft key under Done to finish the selection.
