Hello everybody
Jorge, thank you so much for your help.
I tried changing interchannel delay and the acquisition of two analog
channels was all right (at 2000 rpm), altough this not worked
acquiring three channels.
I calculated the delay this way:
(60/rpm)*(1rev/1024S)*(1/number of channels).
Is
acquires the number of cycles that I expected (also at 2000
rpm), but If I acquire two channels the problem comes back.
I don=B4t know what to do. I really appreciate if somebody can help me.
Kind regards.
Wayuu
Hi everybody
I am using output channel A of a quadrature TTL encoder as external
time base of the acquisition of three analog input signals. I acquire
a total of 1024 scans, one scan for one pulse of the encoder. I use
this system to acquire signal from an internal combustion engine. When
