abbreviations:

• All times are AST
• exp# column: i numbered the experiments 1..N.
  
• The number is used to label some of the binary and plotting files.
• txpwr:
  
• hf: hf tx power measured using spectrum analyzer at the output coupler
• uses 6 sec: avg, max hold, min hold.
  
• 430: 430 tx transmitted power (measured upstairs in the dome).
• movies: link to movies for this experiment
• -->Notes:
• The movies
•  belong exclusively to the experimenter for 18 months from the date  the data was taken (unless they wave this).
• testing movies are public access.
  
• The restricted  movie links  are only viewable locally at AO till then...
  

Transmitted power: (top)

Hf transmitter

The transmitted power was measured for each hf transmitter. The setup was:

• rf output coupler from each tx  goes to rf multiplexor (hanging in front of blue cabinet in hf ctrl room)
• output of multiplexor to anritsu spectrum analyzer.
• anritsu setup:
• 0.. 20 Mhz, rbw 300 khz,
• minhold, maxhold, avg 6 seconds
• the anacom program controls the anritsu and the hfswitch
• 6 secs each tx, then move to next..
• data stored in /share/phildat/hf/yymmdd
• Plots were made for each experiment session (see table above).
  
• Top frame: The power from all 6 tx were summed.
• the 3 colors are sums of: maxhold, minhold, and average.
• Bottom frame: The power from each of the 6 tx plotted (by color).
  
• If the experiment toggled the tx power on/off during a 6 second integration:
• the average value will include the offs
• In this case look at the peak hold value. it will be closer to the actual transmitted power.
  

• black trace: average power for the 6 seconds
  
• red trace: peak hold value for the 6 seconds
• green trace: min hold value fo the 6 seconds.

The table of what we did, has a plot of hf power for each experiment.

430 transmitter

• the top frame is the gregorian dome output power.
• The power for each exp is shown in the table of what we did.
• the power 18mar18 evening ->20mar18 morning is not shown (since no hf).

• does not contain the hf frequency used.
• Plots of drive amplitude and phase for the hf campaign (.ps) (.pdf)
• each page is a separate day
• Top frame has drive amplitude.
• Each tx in different color
• +  show where changes occurred.
  
• the dashed green line at bottom shows rfon (high), rfoff (low).
• Bottom: transmitted phase for each tx
• You can get the mesh position, polarization from this info
• The table has the phase for Tx1 (black color in plots).

Notes: (top)

• signal generator timing.
• a number of experiments used the signal generator for modulating the hf.
• the signal generator would typically start on a hardware 1 or 10 sec tick (depending on what was plugged in upstairs..Usually the 1 sec tick)
• The ticks are tied to the hydrogen maser, so the start time is extremely accurate to the tick.
• the problem may be that an operator was plugging the tick into the siggen to start..
• So the recorded second may be off exactly by one or more seconds.. so you'll have to look at the data to see when the frequency hopped to know exactly which 1 sec tick it was.
