The spectrum analyzer has the C/N measurement function, which is applied to measure the ratio of the carrier
power to noise power.

· [C/N Off On]: Press [Measure]→ [C/N]→ [C/N Off On] to enable or
disable the C/N function.
· [Center frequency]: Press [Measure]→ [C/N]→ [Center Freq] and set
the center frequency of measurement with number keys.
· [Carrier BW]: Press [Measure]→ [C/N]→ [Carrier BW] and set the
carrier bandwidth with number keys. The default setting is 3MHz.
· [Noise Bandwidth]: Press [Measure]→ [C/N]→ [Noise BW] and set the
noise bandwidth with number keys. The default setting is 3MHz.
· [Frequency Offset]: Press [Measure]→ [C/N]→ [Offset] and set the
frequency offset with number keys. The default setting is 3MHz.
The emission mask function is applied to measure whether the signal power exceeds the mask limits, where the
limits are recalled as the masks. The mask can be moved right and left or up and down according to the center
frequency and reference power. In the mask, the limit center is always moved right and left to the center frequency,
and also moved up and down to the reference power point based on the calculated reference power.
