NI 5622 Calibration Procedure
d.
Resample the complex waveform using the MT Resample
(Complex Cluster) VI located at
<LabVIEW Directory>\
vi.lib\addons\Modulation\Analog
.
e.
Concatenate the complex value time-domain data array returned
in step 12d to the end of the previous result.

with
the following parameters:
Handle
: The handle you obtained from
ModtCreateSessionHandle
t0
: Trigger (start) time of the
downconverted I/Q signal data
