SMARTING mobi precision is below its sampling rate (2 ms) – tested with the Delay-jitter (DJ) Test box, found on our website, with Neurobs® Presentation software. However, depending on the platform and the stimulation software, the delay and jitter values can vary. The jitter values may go up to 2 samples. An important notice is that it is possible to measure the delay values for each cellphone (using the DJ Test box), and this delay value is constant for all recordings for that device.
