BODE.EXCITEGAP

Description

BODE.EXCITEGAP controls how often the excitation is updated. The excitation is updated every n drive samples, where n is BODE.EXCITEGAP. For example, if 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

Set excitation update rate to 8,000 Hz:

-->BODE.EXCITEGAP 2

Set excitation update rate to 4,000 Hz:

-->BODE.EXCITEGAP 4

Get excitation update rate (already set to 8000 Hz):

-->BODE.EXCITEGAP 2
