Operation
The spectrum analyzer performs an LO alignment using a detector in the mixer to set the LO Power. During
the alignment the yellow Busy LED turns on. Once the alignment completes, the mixer is ready to make
calibrated measurements since the conversion loss values stored in the mixer are automatically loaded to the
signal analyzer.
