Parameter Lists
This section shows which parameters are global parameters, which are
channel-specific and what types of channels the channel-specific parameters apply
to. Default values are shown for all of these parameters. In addition, each
parameter is categorized as “abort”, “wait”, “immediate” or “glitch” depending on
the behavior when this parameter is changed during a running measurement.
Those with “abort” cause the measurement to abort. Those with “wait” don’t take
effect until the start of the next measurement. Those with “immediate” take
effect immediately. Those with “glitch” take effect immediately and may cause
glitches in the data that is read back or on the source output if the parameter is
applied to a source channel.
