Beam switcher mapping

An analog beam switcher cycles through each of ALFA's 7-beam / 2-pol combinations and is controlled by the iBOB. Here is the mapping:

Here is the mapping from analog input to logical switcher value as defined by the code that programs the iBOB (beam_switcher.c). (I've added the parenthetical beam names based off my notes.)

#define IN00 0xEE
#define IN01 0xED (beam0a)
#define IN02 0xEB (beam0b)
#define IN03 0xE7 (beam1a)
#define IN04 0xDE (beam1b)
#define IN05 0xDD (beam2a)
#define IN06 0xDB (beam2b)
#define IN07 0xD7 (beam3a)
#define IN08 0xBE (beam3b)
#define IN09 0xBD (beam4a)
#define IN10 0xBB (beam4b)
#define IN11 0xB7 (beam5a)
#define IN12 0x7E (beam5b)
#define IN13 0x7D (beam6a)
#define IN14 0x7B (beam6b)
#define IN15 0x77

Note that we do not use IN00 or IN15.

In the data extraction code the beams are numbered 0-13 as defined in setiread.c.

    switch((int)beam_no) 
    {
        case 238:
            beam_no = 0;
            break;
        case 237:
            beam_no = 0;
            break;
        case 235:
            beam_no = 1;
            break;
        case 231:
            beam_no = 2;
            break;
        case 222:
            beam_no = 3;
            break;
        case 221:
            beam_no = 4;
            break;
        case 219:
            beam_no = 5;
            break;
        case 215:
            beam_no = 6;
            break;
        case 190:
            beam_no = 7;
            break;
        case 189:
            beam_no = 8;
            break;
        case 187:
            beam_no = 9;
            break;
        case 183:
            beam_no = 10;
            break;
        case 126:
            beam_no = 11; 
            break;
        case 125:
            beam_no = 12;
            break;
        case 123:
            beam_no = 13; 
            break;
        case 119:
            beam_no = 14;
            break;
        default:
            beam_no = 255;
            break;
    } 
 
    return beam_no;
}

Note: The first and last cases of the switch should never occur as no input is connected to them.

Observing Log

Feb 21, 2009

restarted ssh tunnel again.

Nov 7, 2009

Dead ssh tunnel... restarted with:

ssh -L 3133:lotf.ssl.berkeley.edu:22 casper@casper.berkeley.edu -N -f
  • edited Jan 2010 to reflect new hostname for lotf

Nov 3, 2009

Noticed too frequent file writing:

>>> See rsync output below:

Looks like levels might be set wrong?  Maybe engineering tests at AO?

We also had a problem w/ receiving updated beam switcher values - we did a full restart to see if the problem went away.

Looks like everything came back up ok... We hadn't restarted the ibob in a while, maybe it got into a funky state. ALFA should be back in tomorrow afternoon, at which point we can take another look at the beam switcher problem.

If indeed we have a level issue, perhaps we can ask Luis to add/remove some pads?

Laura lowered thresholder scale in file bee2.config on beecourageous:/home/tfiliba/bin/bee2.config:

> thresholder_scale 80

This corresponds to 20 times the average power. Will go into affect the next time the beecourageous is rebooted.
