Description
AXIS#.BODE.EXCITEGAP controls how often the excitation is updated. The excitation is updated every n drive samples, where n is AXIS#.BODE.EXCITEGAP. For example, if AXIS#.BODE.EXCITEGAP = 2, then the excitation is updated every 2/(16,000 Hz) = 1/8,000 Hz = 0.000125 sec. When measuring a system, update the excitation only as often as the data is recorded.
Example
Code
Set excitation update rate to 8,000 Hz:
--> AXIS1.BODE.EXCITEGAP 2
Set excitation update rate to 4,000 Hz:
--> AXIS1.BODE.EXCITEGAP 4
Get excitation update rate (already set to 8000 Hz):
--> AXIS1.BODE.EXCITEGAP 2
