[:SENSe]:DETector:AUTO?
Switches automatically to the optimum detection type for
typical measurements using the current instrument settings.
The detector type is average if any of these are on:
• Trace averaging when the Average Type is Power (RMS).
The detector type is sample if any of the following
conditions are true:
• Trace averaging is on with average type of video
• Both max and min hold trace modes are on
• Resolution bandwidth is less than 1 kHz, and trace
averaging is on
The detector type is negative peak if any trace is in min
hold and no traces are in max hold.
The detector type is peak if the above conditions are off.
Manually changing the detector function turns Auto off.
Refer to Figure 20 on User’s Guide, which shows a decision
tree of how detection type is determined.
