Lab::Data::Analysis::WaveRunner - Analysis routine for LeCroy WaveRunner/etc. scopes
version 3.772
my $a = Lab::Data::Analysis::WaveRunner->new(stream=>$stream);
create a new WaveRunner analysis object; for use by Lab::Data::Analysis code
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
