Couple Attenuation
During normal operation, the spectrum analyzer is coupled to the reference level. This coupling keeps the mixer
input level at or below a threshold, when a continuous wave signal is displayed on the spectrum analyzer screen so
that its peak is at the reference level.
The CA command sets the threshold to - 10 dBm (or a value specified by KS or ML). The counterpart to the CA
command, the AT command, allows levels less than the threshold value at the mixer input.
OUTPUT 718;"CA;"
The functions of the CA command and the front panel [,,,, key are identical.
