NetStation 'Synchronize' question

H!!

I have a very basic question - What exactly does the NetStation(‘Synchronize’) command do and what are the consequences not meeting the default 2.5 ms parameter?

More specifically, I get the following warring: “NetStationPC synchronization did not succeed within 2.5 ms. Synchronization accuracy is 5.9 ms.”

It synchronizes the Psychtoolbox time with the NetStation host system, so you have proper timestamps. Failing sync will mean greater error in the timestamps, e.g., 5.9 msecs. 2.5 msecs seems to be considered good. There’s also NetStation(‘GetNTPSynchronize’) for some modern EGI systems, so far only tested under Linux afaik.

help PsychPaidSupportAndServices for any further questions.

Is there anyway to improve the accuracy?

I have the same question. Were you able to figure that out? I am facing the same issue. What might be the potential reasons for such sync delays?

Hello everyone,

We use a MATLAB script with Psychtoolbox on a Linux machine to add event markers to EEG data collected using an EGI 128-channel EEG setup. Recently, we’ve started observing synchronization delays of more than 2.5 ms. Could you advise on the potential causes of this issue and how to resolve it?

Thank you for your assistance.
