I was looking for a simple NOT gate the other day. Something that when a +10 V signal is applied to the i/p, sends 0 V to the output. A 0 V input should return a +10V output, much like in a 7400-series TTL device.
This is the truth table I get from the SV Modular NOT:
CV/V/OCT Up Up Down Down IN +10V 0V +10V 0V ----------------------------------- OUT 0V +1.7V -10V -0V
(The “-0V” is how ML Module’s “Volt Meter” reports it.)
I could not use it (without additional modules) because there was no mode where the output switches between +10 and 0 volts. In CV mode the o/p never goes greater than 0V.
The +10 to -10 V is merely changing the polarity (which looks the same on some meters), and (not complaining, just curious by now) what is +1.7 V for? It seems like an arbitrary value, unless there is some other module that expects it that I’m not familiar with. That +1.7 V on the input also appears to be the threshold for switching the output.
Unexpected behaviour makes me nervous, so in the end Stalys’ “8 Not operator” module served my purpose.
