NAME

Lab::Data::Analysis::WaveRunner - Analysis routine for LeCroy WaveRunner/etc. scopes

VERSION

version 3.901

SUBROUTINES/METHODS

new

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

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

Analyze

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

Do 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

$event->{CHAN}->{$channel}->{

	    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 ],

            or 

           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
