#### 3. Known Issues

<para> A delay has been included in Create Arbitrary Waveform in order to prevent Query Interrupted (-410) instrument error from occurring. The error occurs when error query is called from Create Arbitrary Waveform when a small transfer (8-16 points) is sent over ther serial interface.
A delay occurs on the instrument after writing multiple arbitrary waveforms to a 33220A. The instrument has a limited amount of flash memory, and eventually must clean up the memory, this is when the delay occurs. </para> <para>
