Pulses and Gates

2008-10-29 by mritenburg

I understand Buchla does pulses and gates differently than other mfg's. 
I've never paid to much attention to the differences and have just gone 
about my business.  I now plan on using a simple analog computer with 
my 200e and I want to make sure that I understand the pulse and gate 
differences.  At the very least, I have heard that "Buchla modules 
trigger on the falling edge of a gate."  I'm not sure if that is true.

Can anyone quickly run-down the differences between Buchla and, say, 
most other mfg's.

Thanks in advance!

Matthew

the 200e uses a short (<10ms) onset pulse at 10v, and a 5v sustain
level, similar to 200 series but not always identical.

should be very straightforward

that should not be true. if it happens, it is a bug; i've had sporadic
reports of this but nothing specific enough for me to attempt to
verify.

while we are on the subject of pulses , ezra , will i damage my 200e using it with pulses from my 100? I believe the pulses on the 100 are in the 15 volt range ...

probably not a good idea, usually the pulses are read straight into a
microprocessor
