NAME

Lab::Moose::Instrument::SCPIBlock - Role for handling SCPI/IEEE 488.2 block data

VERSION

version 3.790

DESCRIPTION

So far, only definite length floating point data of type 'REAL' is supported.

See "8.7.9 <DEFINITE LENGTH ARBITRARY BLOCK RESPONSE DATA>" in IEEE 488.2.

METHODS

block_to_array

my $array_ref = $self->block_to_array(
    binary => "#232${bytes}";
    precision => 'double'
);

Convert block data to arrayref, where the binary block holds floating point values in native byte-order.

block_length

my $read_length = $self->block_length(
    num_points => $num_points,
    precision => $precision
);

Calulate block length for use in read_length parameter.

set_data_format_precision

$self->set_data_format_precision( precision => 'double' );

Set used floating point type. Has to be 'single' (default) or 'double'.
