 =====Mini Circuits RF Switch and Attenuator===== =====Mini Circuits RF Switch and Attenuator=====
  
 +PURPOSE: We bought several RF switches so we can remotely select antenna pol outputs and direct them into a SNAP board one at a time. This will avoid a lot of manual SMA connector inserting/removal, as well as allow us to do a lot of testing remotely.

 +====New RF Switch antenna assignments====
 +
 +"fxconf.rb" sals shows in none:
 +
 +  1a 1b 1d 1f 1g 1h 2a 2b 2c 2d 2e 2f 2h 2j 2k 2l 2m 3d 3e 3j 3l 4e 4g 4j 4k 4l 5b 5c 5e 5g 5h
 +  (count is 31)
 +  
 +That leaves not used yet: 
 +
 +  1a,1b,1h,1g,2c,2h,2k,2l,2m,3d,4e,5b,5g,5h
 +  (14 count - left out 4j)
 +  
 +Out of the 14 left, using "bestantpols.py --attr tsys-a,tsys-c --details" and "bestantpols.py --attr prms-a,prms-c --details" I shost the next best 8 for the 16x1 RF switch (4):
 +
 +  1a,1b,1g,1h,2k,2m,3d,4j
 +
 +  
 +RF Switch assignments:
 +
 +  (0-1) = 2j,2d,4k,1d,2f,5h,3j,3e (these are the lastest 8 in use)
 +  (2-3) = 2a,2b,2e,3l,1f,5c,4l,4g (these are the original 8)
 +  (4) = 1a,1b,1g,1h,2k,2m,3d,4j (x and y for the 16x1 RF switch)
 +  
 +====Hookup of two 16x1 switches====
 +
 +On Sept 19, 2018 I recieved two 16x1 rf switches from Mini-Circuits. I will be replacing the two 8x1 rf switches with these 16x1 switchs, adding 8 more antennas into the fold.
 +
 +Here is the original definition of the hookups. First number is the RF switch serial number, the second is the attenuator SN:
 +  {"11804220007", "11803290005", "2jx", "2dx", "4kx", "1dx", "2fx", "5hx", "3jx", "3ex", "", "", "", "", "", "", "", "" },
 +  {"11804220005", "11803290019", "2jy", "2dy", "4ky", "1dy", "2fy", "5hy", "3jy", "3ey", "", "", "", "", "", "", "", "" },
 +  {"11807090024", "11802180076", "2ax", "2bx", "2ex", "3lx", "1fx", "5cx", "4lx", "4gx", "", "", "", "", "", "", "", "" },
 +  {"11807090023", "11805160031", "2ay", "2by", "2ey", "3ly", "1fy", "5cy", "4ly", "4gy", "", "", "", "", "", "", "", "" },
 +
 +The SNAPS are hooked up like this:
 +
 +  "snap0" : ['2a','2b','2e','3l','1f','5c','4l','4g'],
 +  "snap1" : ['2j','2d','4k','1d','2f','5h','3j','3e']
 +  
 +Now the hookups are:
 +
 +  "snap0" : ['2a','2b','2e','3l','1f','5c','4l','4g'],
 +  "snap1" : ['2j','2d','4k','1d','2f','5h','3j','3e']
 +  "snap2" : ['1a','1b','1g','1h','2k','2m','3d','4j','5e','2c','4e','2l','2h','5b','5g']
