Table of what we did  (top)

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).
• The movie links  are only viewable locally at AO till then...
  

Transmitted HF power: (top)

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.

    The hf synthesizers generate the amplitude an phase to drive each of the 6 hf transmitters.

• directory holding outputs from hf_synth program with time stamps.
  
• rfon,off, autotoggle setup and start,start times, phases and amplitudes sent to tx's
• does not contain info on cw,sweep info from paul's external generators,.
• 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).

Binary files (top)

    Binary files are made (upon request) of the hf transmitter power as well as the az,za positions during an experiment.
NOTE: no binarys files have yet been made for the may17 campaign (still waiting for juha's request :).

file formats:

• hf tx power:
• link to binary files directory
• filenames:
• hfoct16_USER_hfpwr.dat
  
• data comes from the spectrum analyzer monitoring of the transmitted power (see hf tx power )
• the what we did table has a plot of the tx power for  each experiment session.
  
• For an individual experimenter i put all of there data in 1 binary file
• All binary files are little endian, 8 byte doubles.
  
• record: 3 * 8bytes= 24 bytes
  
•    8bytes         8bytes             8bytes
  
• secs1970   averagePowerKW peakPowerKW
• The spectrum analzyer spends 6 seconds measuring the average and peak_hold power from an hf transmitter.
• It then moves on to the next Hf transmitter. With overhead it takes about 60 seconds to measure all 6   transmitters.
• The avgPower, peakPower (in the binary file) are the sum of that 6 transmitters (so it is the total transmitted power).
• an easy way to read the file is
• get the file size in bytes
• nrecs=filesize/24
• generate double array (3,nrecs)  (or nrecs,3 if you are in python?.. whatever. in memory the 1st 3 doubles are secs1970,avgPwr,pkPwr.
  
• read double array. (my example below is for idl (column major)..
  
• array[0,i]=secs1970
• array[1,i]=average Power KW
• array[2,i]=peak power KW (use this when doing autotoggle since the average may include hf tx off.)
• binary files with pointing information.
• link to binary files directory
• filenames:
• pntI_yymmdd_hhmmss1_hhmmss2.dat
• yymmdd is start date for experiment
• hhmmss1 is the AST starting hour,min,sec
  
• hhmmss2 is the AST ending hour,min,sec for the data
• Data comes from the 1 second monitoring of the telescope position (logged to disc).
• A plot of az,za position for all days: plot of az,za positions for entire campaign (.ps)   (.pdf)
• I put each experiment in a separate file (since the files were bigger).
• All binary files are little endian, 8 byte doubles.
  
• record: 4 * 8bytes= 32 bytes
  
•    8bytes         8bytes       8bytes         8bytes
  
• secs1970   AzDeg         gregDeg       chDeg
• The azDeg is the physical location of the gregorian side of the azimuth arm
• the gregorian azimuth pointing direction is azDeg - 180
• the ch azimuth pointing directio is azDeg.
• Data is recorded once a second (there may be a few missing seoconds in each file.)
• to read the data, look at the hf example (but change the array to 4 by N

Notes: (top)

• Overheating:
• 24may27: starting around 11:30 broad bands were overheating.
• tx2 broad band output dropped to low level (probably thermal protection)
• finally got it back up after putting large fan pointed into door.
• Other broad bands were also very hot.
• 25may17:
• tx 5 overheating. had to turn off.
• 
  
• tx 6: 8 mhz arcing
• 24may17had arcing problem
  
• 25may17 from 12:00 on, ran with tx6 off while using 8 mhz. it worked ok with 5 Mhz.
