Yes, I have an Agilent 5517D which is a frequency stabilized two frequency laser that I got on Ebay. How fast can the counters on the 5I20 count? I would need a pair of perhaps 32 bit counters that can count at more than 4 MHz and can be read out simultaneously. (Actually, copied into

Peter, What type of counter do you use that can propagate a carry over 32 bits in 10 nsec? That's what you need to count at 100 MHz. Ken Peter C. Wallace wrote: On Sun, 20 Dec 2009, Kenneth Lerman wrote: Date: Sun, 20 Dec 2009 10:54:46 -0500 From: Kenneth Lerman

Mike, Have a look at this item - this will safely break out your signals from the parallel port http://tinyurl.com/yh6j93r and this will give you enough parallel ports to drive up to 9 motors... http://tinyurl.com/yzn2b9z Best wishes, Ian ___ Ian W. Wright Sheffield

[Emc-users] Multiple Servo tuning problems.

2009-12-20 Thread Dustin Monroe
Hello, First i will start with my setup. I have a Milltronics partner 4 retrofit that is almost complete minus the servo tuning. I am using a mesa 5i20 board with 7i33 and 7i37. and AMC 30a8 amplifiers. My first issue is with the amp tuning, I have them pretty solid, but all axis move slowly
