Re: Encoder Logic Range?

Yes, I am quite sure we have the right encoders, as our four were ordered in two pairs, one from the KoP and one from Andy-Mark on the first or second week of build. According to the 'scope, the two channels' waveforms were roughly a quarter period or so opposed, however the range was very clearly bounded by [-1V,1V]. This is odd, because the data sheet for the sensor itself says that the signal should be the expected [0V,5V]. I can build a translating circuit, but I should not have to, though finding transistors that can switch at ~8.1MHz may be (ahem) interesting. Any ideas?
