Programs are a set of frequencies, separated by a comma. Here is an example:
A sweep has a starting and ending frequency. It looks like:
Here the sweep starts at 100 Hz and increases the frequency in the generator until it hits 200 Hz.
So if you look at a program, if there is a minus sign in the set of frequencies, it contains a sweep.
If you are unsure if a program has a sweep, try loading it into a GenX offline program. If it does not fail, there is no sweep.
