capabilities including triggered list mode for both wide and narrow band lists. The list modes
provide the fastest switching speeds between points but require a CSV list of appropriate
parameters.

Narrow Band list functions.
Disable Modulation returns the SET menu (below) control for frequency, power, phase offset,
and input reference.
