Max sampling is 960 Hz when 8 hours recording.
Max frequency: set filter cut off frequency at -3db.
frequency range : sampling frequency to 1/10 of frequency.
ex : when 120 Hz sampling, 12 Hz to 120 Hz is filter cut off frequency.
Filter high cutoff frequency ratio.
Default is 0.3333.
range is 0.1000 .. 1.0000
ratio by sampling frequency.
ex : when 120 Hz sampling -> 120 Hz X 0.3333 = 40 Hz cutoff frequency
Device configuration: setup Device channel number,
Filter high cutoff frequency ratio: set up high cutoff frequency ratio for internal Filter

5.4.1: Filter mode
AC DC CUT: Turn on and select the frequency range
Coherence calculation level: coherence calculation up to selected power level.
Show Reverse Polarity to Play display:
Coherence shows 0..90 degree phase. In case phase is over 90 to before 360 degree then coherence shows 0 %, this mean 1/4 phase can see as coherence.
Use this option setup, show same L channel wave to CH 3, and R channel wave make 180 degree phase to CH 4 as play mode display in the Brain wave display window. ( only brain wave display window ). When select Play mode display then shows 180 degree Polarity sift wave. This way easy to see coherence difference between not phase shift and 180 degree phase shift at once. this mean 1/2 phase can see as coherence.
This setup is only for Live recording brain wave. Also can not play brain wave in the play mode display.
Set Revers Polarity for Brain wave and Sound wave.:
Use this Revers Polarity setup makes 180 degree phase between L & R channel to eliminate 180 degree phase difference. When use “ Show Reverse Polarity to Play display:” no need to set this option for Brain wave.

Upload brain wave:
type "Upload ftp address" : "ftp://xxx:@yyy.com/IBVA4data/
this mean brain wave data will up to IBVA4data folder in the yyy.com at user name xxx.
type "username" and "password".
then click "Upload Start". in case upload succeed then "OK" will show ON.
To upload brain wave need to set up IBVA4 as record mode (live mode).
to stop Upload, un check "Upload Start".
Download brain wave:
type "Download http address" : "http://yyy.com/~xxx/IBVA4data/
this mean brain wave data will down load from IBVA4data folder in the yyy.com/~xxx/.
no need to use "username" and "password" permission for this process.
then click "Download Start". in case download succeed then "OK" will show ON.
To see brain wave need to set up IBVA4 as play back mode.
to stop download, un check "download Start".
some case need to re setup play time point to see brain wave.
Set play time point about 5 to 10 second before is safety to see brain wave.
*********
Receive brain wave data is time sync from sender's time point.
From sender, IBVA4's recording time is 01:23:45 (upload brain wave data and time),
then
Receiver IBVA4's play back time is also 01:23:45 (down load brain wave data and time),
About 2..5 second difference in-between sender and receiver.
*********
Depend on Internet connection speed and condition, some part of receive brain wave data may lost.
