Data throughput problems
•
If decreasing the number of analog input channels or the
sampling rate improves performance, you likely have a data
throughput problem. Verify that the digitizer is connected to a
high-speed USB 2.0 port on your computer. See
Digidata 1550 Digitizer on page 8
. If the digitizer is connected to
a USB hub, remove any other devices connected to the hub, or
bypass the hub.
•
Try the digitizer on a faster computer. CPU speed is only one part
of the equation. Other relevant components include hard disk
speed, RAM speed, and front-side bus speed.
•
To improve data-throughput related acquisition performance
problems in Clampex or AxoScope, try the following:
In
Configure > Lab Book Options
, select
Never log any
events
.
In
Configure > Program Options
, select
Disable screen saver
during data acquisition
