Lab::Moose::Instrument::VNASweep - Role for network analyzer sweeps.
my $data = $vna->sparam_sweep(timeout => 10, average => 10, precision => 'double');
Perform a single sweep, and return the resulting data as a 2D PDL. The first dimension runs over the sweep points. E.g. if only the S11 parameter is measured, the resulting PDL has dimensions N x 3:
[ [freq1, freq2, freq3, ..., freqN], [Re(S11)_1, Re(S11)_2, ..., Re(S11)_N], [Im(S11)_1, Im(S11)_2, ..., Im(S11)_N], ]
This method accepts a hash with the following options:
timeout for the sweep operation. If this is not given, use the connection's default timeout.
Setting this to
$N, the method will perform
$Nsweeps and the returned data will consist of the average values.
floating point type. Has to be 'single' or 'double'. Defaults to 'single'.
The following methods are required for role consumption.
my $array_ref = $vna->sparam_catalog();
Return an arrayref of available S-parameter names. Example result:
['Re(s11)', 'Im(s11)', 'Re(s21)', 'Im(s21)'].
my $binary_string = $vna->sparam_sweep_data(timeout => $timeout)
Return binary SCPI data block of S-parameter values. This string contains the
sparam_catalog values of each frequency point. The floats must be in native byte order.
