11.2. Limits
Real-time acquisitions on file are limited by the transfer rate between the inputs and the saving
hardware liek an internal hard disk or a USB key.
This limit depends on the type of the acquisition file: binary or ascii.
11.1.1.Binary file
The maximum transfer rate is 1,200,000 bytes/s (1.2 Mbyte/s).
In order to know the number of channels that you can record for a given acquisition period, you
have to calculate:
number of channels = 1,200,000 x acquisition period
example: acquisition period: 10 s
number of channels = 1,200,000 x 10 s = maximum 12 channels
11.1.2.Ascii file
The maximum transfer rate is 1,000 bytes/s (1.0 Kbyte/s).
The minimum acquisition period is 1ms.
In order to know the number of channels that you can record for a given acquisition period, you
have to calculate:
number of channels = 1 000 x acquisition period
