The spectrum analyzer provides the function of carrier-to-noise ratio measurement to measure the ratio of carrier
power to noise power.

The emission mask function is to recall the limit line as a mask to measure whether the signal power passes
through the mask. The mask can move up and down and side to side according to the center frequency and
reference power. The mask always moves the center point of limit line side to side to the center frequency, and
moves the center point up and down to the reference power according to the calculated reference power.
