Lab::Data::Analysis::TekTDS - Analysis routine for Tektronix TDS1000/TDS2000/etc. scopes


version 3.653



my $a = Lab::Data::Analysis::TekTDS->new(stream=>$stream);

create a new TekTDS analysis object; for use by Lab::Data::Analysis code


my $event = $a->Analyze($event[, optionshash]);

Do TekTDS analysis on an event (passed by hashref); the results of the analysis are stored in the hashref, and the hashref is returned.

If there is an error, "undef" is returned.

The analysis results can be found in


            CHAN => channel name,

            X => [ ... x values ... typically times ],

            Yunit => unit for Y scale,

            Xunit => unit for X scale,

            ID => ID string describing waveform,

            START => $jstart        ... $X->[$jstart] is first sample
            STOP => $jstop          ... $X->[$jstop] is last sample

            two options:

           Y => [ ... y values... typically voltages ],


           YMIN => [ ... min y values ...], YMAX=> [... max y values..],

The YMIN,YMAX arrays are returned for 'envelope' type waveforms.

To get the usual time/voltage pairs:

      for ($j = $ev->{CHAN}->{CH1}->{START};
        $j <= $ev->{CHAN}->{CH1}->{STOP}; $j++) {

        $t = $ev->{CHAN}->{CH1}->X->[$j];

        $v = $ev->{CHAN}->{CH1}->Y->[$j];


Analysis options:

    dropraw => [def: 0]    ... drop the raw analysis intermediate results
    interpolate => [def: 1] ... create a Yfunc interpolation function
    print_summary => [def: 0] ..print a summary of waveform info
