| Aug 3 1996 04:07:05:050PM | Steve Wolfe | Done with gas tests. State to stdby, log frank out.
Load 960227003 into model for Monday. | |
| Aug 3 1996 11:53:40:660AM | 960803001 | Steve Wolfe | Test shots for willy to check out gas system. Seg 1 only.
Board seems to work, but there is a 150msec delay before gas show up on ratiomatic. |
| Aug 3 1996 12:04:10:720PM | 960803001 | Steve Wolfe | 960803002. Test of Willy board in bypass mode
Pulses again. and a decay after the fizzle detector shuts it down |

| Aug 3 1996 12:11:14:090PM | 960803003 | Steve Wolfe | 960803003. Test of Willy board in bypass mode
100msec ramp from 0- 100V looks like a slow turn-off reponse |
| Aug 3 1996 12:12:21:560PM | 960803003 | Steve Wolfe | 960803003. Test of Willy board in bypass mode
100msec ramp from 0- 100V looks like a slow turn-off reponse Still no gas on ratiomatic till .11, after drive pulse is off. |
| Aug 3 1996 12:22:57:120PM | 960803004 | Steve Wolfe | 960803004. Test of Willy board in bypass mode
100msec ramp from 0- 100V, start high, go low this time Pressure starts up at 60msec. There still seems to be a lag in turn-on and turn-off. |
| Aug 3 1996 12:30:41:140PM | 960803005 | Steve Wolfe | 960803005. Test of Willy bypass (wire) board
Seems to be about 1msec delay from Mout to downstairs (AFOL) Gas on ratiomatic comes in at ~45msec. |
| Aug 3 1996 01:24:51:640PM | 960803006 | Steve Wolfe | 960803006. Test of Willy pulse board
Removed 10uF cap at input to comparator. Response now is as advertised. |
| Aug 3 1996 01:31:41:990PM | 960803007 | Steve Wolfe | 960803007. Test of Willy pulse board
30V/300msec ramp No gas on IGT . Forgot the fd, only got to 17% |
| Aug 3 1996 01:44:27:360PM | 960803008 | Steve Wolfe | 960803008. Test of Willy pulse board
30V/300msec ramp No gas on IGT Move waveform earlier to avoid fiz. 3e-7T comes very late. Had been getting 5e-5T |
| Aug 3 1996 01:57:41:700PM | 960803009 | Steve Wolfe | 9608030009. Test of Willy pulse board
60V/300msec ramp No gas on IGT Move waveform earlier to avoid fiz. It seems to open somewhere between 40-50% width, i.e 2.5-3msec minimum width. Willy wants to try setting the minimum width to 2msec. |
| Aug 3 1996 02:37:49:210PM | 960803010 | Steve Wolfe | 9608030010. Test of Willy pulse board
back to 30V/300msec ramp Move waveform earlier to avoid fiz. Minimum width set to ~2msec. Valve seems to be opening with about 10 "volt" programming, now. |
| Aug 3 1996 02:45:02:160PM | 960803010 | Steve Wolfe | 9608030011. Test of Willy pulse board
20V, 100msec square pulse. Minimum width set to ~2msec. 2.6e-5 peak pressure |
| Aug 3 1996 02:45:10:200PM | 960803011 | Steve Wolfe | 9608030011. Test of Willy pulse board
20V, 100msec square pulse. Minimum width set to ~2msec. 2.6e-5 peak pressure |
| Aug 3 1996 02:49:14:860PM | 960803012 | Steve Wolfe | 9608030012. Test of Willy pulse board
10V, 100msec square pulse. Minimum width set to ~2msec. 1.75e-5 peak pressure |
| Aug 3 1996 03:08:49:740PM | 960803013 | Steve Wolfe | 9608030013. Test of Willy pulse board
5V, 100msec square pulse. 1.2e-5 Torr peak It is quite linear, which Willy thinks is great, but I think this is too sensitive. It will probably put out some gas at zero, although a negative will turn it off hard. Try to reduce the minimum pulse width a bit more. |
| Aug 3 1996 03:22:00:710PM | 960803014 | Steve Wolfe | 9608030014. Test of Willy pulse board
5V, 100msec square pulse. Reduce minimum to 0.8msec (there seems to be nothing between 2 and .8?) I expect this to give no gas No visible rise on IGT. Got small pulses but no rise on ratiomatic |
| Aug 3 1996 03:27:58:200PM | 960803015 | Steve Wolfe | 9608030015. Test of Willy pulse board
20V, 100msec square pulse. Reduce minimum to 0.8msec (there seems to be nothing between 2 and .8?) Got 5e-7 peak pressure. This is essentially the threshold level. Actual voltage out is 1.75V out of the AFOL |
| Aug 3 1996 03:33:47:360PM | 960803016 | Steve Wolfe | 9608030016. Test of Willy pulse board
40V, 100msec square pulse. Reduce minimum to 0.8msec (there seems to be nothing between 2 and .8?) 2.65e-5 T peak |
| Aug 3 1996 03:42:05:550PM | 960803017 | Steve Wolfe | 9608030017. Test of Willy pulse board
60V, 100msec square pulse. Reduce minimum to 0.8msec (there seems to be nothing between 2 and .8?) 5.8 e-5 peak. |
