I’m trying to import data from a PCSGU250 to Matlab, which is working only at low update rates.
highest update rate I can get is about 5 Hz.
I’ve tried both the driver on the disc (1.0.0.0) and the one on the site.
Also tried a shorter USB cable, but nothing seems to increase the update rate.
as mentioned in http://forum.velleman.eu/viewtopic.php?f=10&t=3048&start=30
It also doesn’t make a difference if I read both channels or only one.
Due to the limited USB speed the transfer of the data from the oscilloscope to the PC is such time consuming.
Theoretical lowest transfer time for the PCSGU250 data (2x4096 bytes) is 128ms. Maximum theoretical update rate is so about 8Hz.
I’m sorry, the update rate can’t be increased.
