6: A2D/DATEL/FILTERS /none Mon 01-Aug-1994 18:41:11 GMT problem with new 10 hz/-5 volt filters:
problem with new 10 hz/-5 volt filters: 
 
  The new filters, for 10 hz and 1/2 
gain, will not work with a voltage input 
getter than 10 volts to the second stage 
amplifier. As an example: 
  input: 0 to 1 volt 
  gain: stage 1 - 10 volts 
	stage 2 - 2 volts with -5 volt offset 
 
  output: will work until input gets above 
	  .5 volts then the second stage  
 	  amplifier saturates. 
 
  This filter board was to be used on the 
PVM instruments and the humitter sensor, however, 
the outputs go too high! Will go back to 
a standard 10 hz filter and use a gain of 1.

Marigold, rain detect change: 
 
  The rain detect signal has been 
changed. The output range is 
0 to 12 volts. The gain stage was 
changed to gain of 1 with a -5 volt 
offset. The prep.config range is now 
-5 to 5.

Marigold: Changed for Peter's 3 Analog Channels 
 
Changed AD Gain Jumpers/Operating-files accordingly. 
 
These channels are being used for Peter's intercomparisons and 
miscellaneous tests. 
Analog jumpers changed	ch112: W4,W2 Pulled gain was 5, now 1 
			ch113: W4,W1 Pulled gain was 50, now 1 
 
Range is now -5 to +5. 
 
Changed prep.config.raw 
was.... 
s=marigold:112 c=linear(.0030517578,.0) d=(t).peter.2.5m r=1  m=(0:100) 
s=marigold:113 c=linear(.0030517578,.0) d=(rh).peter.2.5m r=1  m=(0:100) 
s=marigold:114 c=linear(.00015258789,.0) d=(ref).peter.2.5m r=1  m=(0:5) 
 
now 
s=marigold:112 c=linear(.00015258789,.0) d=(chanA).peter r=1  m=(-5:5) 
s=marigold:113 c=linear(.00015258789,.0) d=(chanB).peter r=1  m=(-5:5) 
s=marigold:114 c=linear(.00015258789,.0) d=(chanC).peter r=1  m=(-5:5) 
 
 
 
Changed prep.config also 
was.... 
s=marigold:112 c=linear(.0030517578,.0) d=(t).peter.2.5m r=1  m=(0:100) 
s=marigold:113 c=linear(.0030517578,.0) d=(rh).peter.2.5m r=1  m=(0:100) 
s=marigold:114 c=linear(.00015258789,.0) d=(ref).peter.2.5m r=1  m=(0:5) 
 
now 
s=marigold:112 c=td_linear("chanA.peter.CACHE94") d=(chanA).peter r=1  m=(-5:5) 
s=marigold:113 c=td_linear("chanB.peter.CACHE94") d=(chanB).peter r=1  m=(-5:5) 
s=marigold:114 c=td_linear("chanC.peter.CACHE94") d=(chanC).peter r=1  m=(-5:5) 
 
Added Calib files for time delay linear stuff: 
chanA.peter.CACHE94 
chanB.peter.CACHE94 
chanC.peter.CACHE94 
#.... 
# Calibration file used by td_linear for one (of 3) "spare" channels

1994 229 003000		0.00015258789   0. 
 
 
 
Changed did.config 
# different aliases to the same analog channels

rh.peter.2.5m		290

Changed scripts/covar_marigold and restarted it: 
Added new covar group; 
set g[15] = "-a chanA.peter:chanB.peter:chanC.peter" 
 
 
Added to netcdf covar output files 
Used create_cdl.csh to create the netcdf files and 
put that into covar. 
Added the line: 
M chanA.peter(V) chanB.peter chanC.peter 
to create_cdl file before executing it. 
 
 
Changed file cov2netcdf.csh 
to define the new variables 
for the netcdf groups: 
  case marigold: 
    set g = ( \..... 
	"-a chanA.peter" \ 
	"-a chanB.peter" \ 
	"-a chanC.peter" \
