Spectrum Stitching
When Spectrum Stitching is turned on, multiple acquisitions overlapped in
frequency domain will be performed and then combined to get wide band IQ data.
This enables the instrument to capture and analysis wider signal, it may slow down
the measurement speed and it requires the signal to occupy the major part of the
analysis bandwidth.
Note: accurate trigger is needed to align multiple acquisitions in time domain, and
input signal need to be repeated and aligned with trigger precisely.
