# RS232HIST histogram summary of last 21 days read Thu May 26 09:00:37 2005 # # column 1: x axis reference (0...6) # column 2: number of TrueTime "ET" (TTET) data sequences in RS232 fifo # before readout by gpstrg # column 3: number of Motorola 1PPS data sequences in RS232 fifo before # readout by gpstrg # # columns 2 + 3 should ideally only have values in the "1" row (column 1 = 1) # meaning that each 1PPS data word was read out in sequence by gpstrg. # No data in column 2 (all 0) means there were no spill triggers in the # observation time. # If there are values in "2" or higher row then gpstrg had experienced # some timing delay preventing it to read the RS232 port(s) fast enough. # If row "0" shows values for column 2 or 3 then gpstrg was expecting # new data in the RS232 fifo but found it empty (should compensate with # the values in "2" or higher rows). # #---------------------- 0 0 2720 1 0 1785500 2 0 2720 3 0 0 4 0 0 5 0 0 6 0 0 #---------------------- # sum: 0 1790940 total samples # good: 0 99.70 % sequential readouts # bad: 0 0.30 % skipped or missed readouts
