GSV-1A8USB K6D, Programmiren in MATLAB

Beitragvon Gan Li » Fr 4. Apr 2014, 09:19

Hallo,
ich bin schon in der Lage, die Daten in MATLAB zu lesen. Wie kann ich "set zero" in MATLAB? Bitte antworten Sie im Detail, wie möglich.
It will be better in English. ;)

Hello,

there is no command "setzero" available with GSV-1A8USB.
There is only a digital input, which makes setzero for all 8 channels at PIN35 of Sub-D37.
best regards

How the "set zero" function in software "GSVmultichannel" works? Only use the USB-port.

Hello,
IO Port 1.3 is controllable per software.
This digital output is connected with the digital input "set zero" of the eight analog amplifiers.
With output high signal at IO Port 1.3 the eight channels will perform a set zero.

This is the way, how GSVmulti makes set zero.
Best regards

Which kind of data filter should I use? There is too much noise.
I use a low-pass filter, but it works not so good, especially when the load force is zero. Maybe my parameters setting is not quite right?
Thanks a lot! :)

Hello,
the best way is to sample with maximum sample rate (200kS/s) and to use sliding average filter.
Sometimes noise is caused by noisy USB ground. The use earth cable of GSV-1A8USB.
