Be sure to have the general order of commands as listed on the Basic Structure page in the Getting Started section.
It is recommended that you always stop the memory at the beginning of a new chirp definition.
When downloading data into the DSM, create a delay between the time you start downloading and the time you start the memory. This will ensure that all of the data that you have stored on the computer will be downloaded correctly to the DSM. For longer Memory Depth chirps, this is especially important. The delay will be dependent on your system resources. You can experiment with the delay time by using the DSM GUI by downloading waveforms of various Memory Depth.
