Gary is getting ready to do some shot cycles to test the diborane
puffing system. 

Load from 1060202004 and copy Bside upper pulse (Pg2) to 
OUtput 19 (diborane).
Note that the dpcs tree from this day is invalid, so I've
got the current (1060210017) dpcs

Shot#1: trying to puff Helium through the diborane system
using output 19 (loaded using the test version of PCS). 

Going ahead with the test pulse. 
No gas that I can see on live ratiomatic, but may have
been not set up correctly in PLC screens.

No it also didn't put out an output. Fizzle is ok at 
1.7sec I think, so that's not it.

SHot#1 failed to puff because of a significant BUG!
dpcs_concatenate.fun is returning an error because I 
only drew a waveform in segment 2 and so the segment 1 
v19:output gave an error. Therefore dpcs output zeros for
that channel

For shot#2: Put a point in seg_01:v19 so the output will
exist and we should get outputs. 

It looks ok in the model tree, should work this time.

Shot#2: Try again with a flat waveform in seg01.
OK, got gas. Pulse is from 0.3 to 0.8 as programmed. 
Ratiomatic shows 1mTorr (gauge, uncalibrated) with 
the rise between 0.4 and 0.9, so that sounds like there is 
about a 100msec delay somewhere.
