USB-2408 TC Noise

Alex Breves


I am struggling to get reliable tc data from my USB-2408. I am using that close to high voltage inverters (up to 1000V DC input) with switch frequency of 20KHz+. I also have another TC data acquisition system (from a competitor) that doesn't suffer of the same illness.

If I operate my inverter up to +/- 50V DC, the noise is minimum. Above that, the signal is useless.
