Modifying the Stimulus | 60
Another commonly modified variable is the Gate Time for tone stimuli. Typical ABR gate
times are 0.2 ms - 2 ms.
Note
Changing the gate time will change the size and shape of the response.
Important
The changes will only be saved in the configuration file, if the Lock SigGen Files check box is selected in the
Stimulus Setup dialog bog. If this check box is not selected, any changes to variables or SGI selections for
presentation will be lost.
Also, if you select the Reload Files button in the Stimulus Channel Setup window, the changes will be overwritten
in favor of the values in the .sig file.
